X.One® Extreme Series is relatively thin, thinner than most similar products in the market. To be exact, it is only at 0.28mm, therefore may not pose any problems with casings.
Furthermore, our fullscreen screen protectors are 2.5D edge version(case compatible).
However, X.One® do not recommend customers to put on any casing with highly raised bezel designed. Raised bezel designed casing raises above the smartphone’s display screen as providing impact protection to the smartphone, but it may peel off the screen protector.
