Bumpy - our smartphone case

To effectively protect your technological jewel, we don't offer just any smartphone accessory, but only TPU smartphone case (and screen protectors, but we'll talk about that here). TPU, short for thermoplastic polyurethane, combines the strength of plastic with the flexibility of silicone! It has a unique molecular structure that offers high resistance to shocks, abrasion and scratches. It is also highly resistant to temperature variations, and much more...

In summary, choosing a protective TPU shell from ouff.ch is great because :

  • it doesn't slip out of your hands
  • it absorbs shocks
  • it resists wear and tear
  • it has a high degree of transparency > it doesn't "disguise" your smartphone as a dragqueen!
  • it remains flexible at low temperatures
  • it resists to high temperatures
  • it is resistant to UV rays
  • it is resistant to solvents and oil
  • it is odorless
  • it is easy to clean


A protective shell for your smartphone made of TPU offers you a good level of protection, it won't fall off your hands, because it doesn't slip, it's robust, and it's durable! In addition, our Bumpy model with its four shock absorbers in each "corner" increases the shock absorption. With their rectangular shape, smartphones (almost) never fall on a full side. This means that it is (almost) systematically the corners that take the shock first! And it is precisely in these corners that the shock absorber is located! The other advantage is that the extra thickness brought by these shock absorbers will not bother you, because you hold your smartphone on the sides, where the extra thickness generated by our protective shell for smartphone Bumpy is minimal!

For all these reasons, we at Ouff have opted for this protective shell exclusively! And we're sure you'll love it as much as we do (plus, shipping is free)! And don't forget to protect the screen too... :)
