What you actually need to know about personalised tough phone cases
We've been making tough cases since 2016. Here's the straight version: how drop testing actually works, what the raised screen lip does, why we use port covers, and where tough cases aren't the right call.
What a personalised tough phone case is
A tough case is a dual-layer protective case designed to survive real drops. Soft inner layer absorbs the impact, hard outer layer takes the surface abrasion. The back panel is printed with whatever design you upload, so the case carries something personal instead of looking like a generic black rugged shell.
These are bulkier and heavier than snap or bumper cases. That's not a flaw; it's the whole point. The bulk is doing protective work. If your phone genuinely gets dropped (site work, kids using it, outdoor sports, anyone whose phone has a cracked-screen story they'd rather not repeat) this is the format you want.
What we make them from
Two materials, layered. The inner shell is TPU (thermoplastic polyurethane), a soft rubbery plastic that flexes on impact and snaps back to its original shape. The outer shell is rigid polycarbonate, hard enough to take detailed print without flexing or distorting the image.
The TPU does the impact absorption. When the case takes a knock, the TPU flexes inward, converting kinetic energy into heat that dissipates through the case material. The phone inside experiences a much smaller, slower force than the original impact. Same physics as a car crumple zone, just scaled down.
The polycarbonate outer takes the surface abrasion (scratches from concrete, kerb stones, gravel) and keeps the printed design protected. Our UV-cured ink is rated for 12+ months of full sun before any visible fade, but because the print sits slightly recessed below the raised case edge, it sees less abrasion than a snap case print and tends to outlast the phone it's on.
Drop testing: what "2m drop tested" actually means
Most "rugged" cases on the high street cite MIL-STD-810G. That's a US military transit standard. The test: drop the cased device 26 times from 4 feet (about 1.22m) onto a 50mm plywood-over-steel-over-concrete surface, hitting every face, edge, and corner. A passing case means the device inside still works after all 26 drops.
We test ours to a stricter version. 2m drops (about 6.5 feet), onto unsanded concrete, hitting all 14 contact points. The phone inside has to remain fully functional afterwards: touchscreen working, all cameras working, speakers, microphone, buttons, all of it.
What this means in real-world terms: a personalised tough phone case will survive being dropped from chest height onto a tarmac driveway, off a desk onto a wooden floor, off the bonnet of a car onto kerb stone. It will not necessarily survive being thrown off a multi-storey car park onto granite. There are limits to physics.
The raised screen lip, and why 1.5mm matters
Face-down drops account for most cracked screens. The screen is the most expensive single part on a modern phone (typically £150-£400 to replace) and the most likely to break. A case with no raised lip leaves the screen flush with whatever surface you put it down on, and when the phone falls face-down, the glass takes the full impact.
Our tough cases have a 1.5mm raised lip around the entire screen edge. When the phone lands face-down, the case edge touches the surface first; the screen sits 1.5mm above it, suspended above the impact zone. It's not a guarantee against every face-down drop, but it stops the vast majority of them.
Port covers, and why most cases skip them
The USB-C port and headphone jack (on phones that still have one) are the easiest path for dust, sand, grit and water spray to get inside the device. Once they're in there, they cause corrosion, and corrosion is the slow death of every smartphone.
Most cheap tough cases leave these ports open. Ours have silicone flap covers that seal flush when not in use, then pop out of the way when you plug in a cable. They're easy to lose track of if you don't actively use them; we recommend getting in the habit of flipping them shut after every charge.
Not waterproof. We don't claim IP67 ratings because we don't pressure-test in water chambers. But enough to stop a sandy beach day, a building site, or a freak shower from frying your charging circuit. The covers also keep pocket lint from packing into the port, which is the other slow killer of phones.
Tough vs the other three case types
- Wallet case: Folio cover, card slots, screen protection, but almost no drop protection. Choose wallet for daily-life utility; choose tough when survival actually matters.
- Snap case: Slim, light, full 3D wrap print. No drop-test rating. Choose snap if you don't drop your phone and just want it personalised.
- Bumper case: Flexible TPU edge plus printed back panel. Better edge protection than a snap, weaker for face-down or back-flat drops than a tough. Bumper is the slim-middle-ground option; tough is when slim isn't the priority.
- Tough case: Six-faced protection, raised screen lip, port covers, 2m drop tested. Bulky, heavy. The right call when actual drops happen.
What makes a good photo to print on one
- 1500 by 1500 pixels minimum. The print area on a tough case is smaller than on a snap or wallet (the raised edges and port covers reduce visible surface), so resolution requirements are similar.
- Bold central designs print best. The raised case edges create a slight frame around the print, so designs with strong focal points (a face, a logo, a single subject) work better than busy edge-to-edge patterns.
- Dark backgrounds hide scuffs. Tough cases get scratched in real use, and darker print backgrounds disguise these scuffs much better than light ones over months of carry.
- Keep text away from the edges. Anything within 5mm of the case edge looks slightly tucked under the raised lip; keep type and important detail in the central 80% of the print.
Keeping it nice for years
- Pop the port covers regularly. Flip them open every couple of weeks, let any accumulated debris fall out, wipe inside with a dry cloth.
- Don't pull the case off daily. The TPU inner shell is sized precisely for your phone, and repeated removal stretches it. Install once, leave it on for the life of the phone.
- Wireless charging still works. Even at 10mm total thickness, our tough cases stay within MagSafe and Qi tolerance. Don't bother removing the case to charge.
Good gift use cases
Tradespeople and site workers tend to love bold company logos or trade-related graphics. The kind of thing that looks the part on a phone living in a tool pouch.
Outdoor adventurers go for mountain ranges, climbing routes, ski resort logos, anything that represents the kind of activity they bought the case for.
Parents handing phones down to kids: the tough case adds the drop survival the kid will absolutely need; the personalised print adds something the kid will actually like enough to keep using it.
Couriers, delivery drivers, taxi drivers: phones get dropped five-plus times a week in these jobs. A tough case with a custom design beats a generic black shell, both for protection and morale.
How we ship
Every personalised tough phone case is assembled, printed and dispatched from our UK workshop. Order before 12pm on a working day and it ships that afternoon on tracked Royal Mail, free UK delivery. International shipping at checkout.
We stock tough cases for the most popular phone models and source quickly for the rest, so most orders ship within 24 hours rather than the multi-week waits you'll see on cases shipped from overseas.
If it arrives wrong
Print and construction are both guaranteed for the lifetime of your phone. Anything wrong, send us a photo within 30 days, we reprint or reassemble and reship free. The original stays with you. No returns to organise.
