How We Choose Our Phone Cases (Not All Pass the Test)

At MonoCases, we don’t just pick any phone case and throw it on the shelf. Behind every product in our store is a clear process — one that filters out the gimmicks, rejects the bulky, and champions the perfect balance of form and function.

Spoiler: Not all cases pass the test.

Here’s exactly how we choose the phone cases we sell and why it matters to you.

We Start With the Hands-On Test

No matter how good a case looks online, we don’t take a supplier’s word for it. We get samples. We try them. We drop them (on purpose). We put them in our pockets, on desks, and in backpacks. We hand them to friends.

We ask:

Does it feel good in the hand?

Is it slippery? Grippy? Cheap-feeling?

Do the buttons work like they should?

Does it protect the camera and screen?

If it doesn’t feel premium, it’s out no matter how trendy it looks.

 

We Stress-Test Materials

We don’t believe in cases that yellow in two weeks or warp with a little heat. Our materials are tested for real-world wear, including:

UV resistance (especially for clear cases)

Scratch resistance (daily use, keys, bags)

Elasticity (no stretching out over time)

MagSafe strength (yes, we test magnetic hold)

Only cases made from high-quality TPU, polycarbonate, or hybrid blends make it past this round.

Fit and Precision Check

You’d be shocked how many cases have sloppy fit issues — loose corners, stiff buttons, off-center cutouts.

So we test every candidate on actual devices, checking:

Seamless fit with no gaps

Responsive, clicky buttons

Proper camera lip height

MagSafe alignment and strength

No audio obstruction or port misalignment

A 1mm misalignment? Instant rejection.

NOTE: All our cases are tested on iPhone 16 PRO models in 2025.

Price-to-Value Ratio

We don’t believe in €50 cases just because they’re “designer.”

And we don’t believe in €5 ones that crack in a week.

Every case we sell must deliver real value for money, meaning:

You get quality materials and finish at a fair price

You’re not paying for branding fluff

You won’t have to replace it every month

In short: We choose cases we’d buy ourselves and gift without hesitation.

A Curated Collection That Earned Its Place

MonoCases isn’t a marketplace. It’s a selection curated by people who are obsessed with getting it right.

We’ve rejected dozens of supplier catalogs, passed on hundreds of mediocre designs, and said no to even popular trends when they didn’t pass our tests.

What’s left is a collection we’re proud to put our name on — and one that you can trust to protect your device without sacrificing style.

Because when we say form first, function always, we mean it.
