Introducing the Card Holder :Our product has been optimized with a bottom opening that makes it easier to insert cards and easily push out from the bottom, improving the issue of difficulty in removing cards in other products. second optimization is to replace the adhesive with a brand new one, which is suitable for use with phone cases.
It will become more and more durable over time. If u don't want to use it anymore, it can be easily removed without leaving any adhesive residue, and does not support repeated pasting.
