I bought it because I liked it after seeing my junior use it while diving. I like it because it is waterproof and light. I like the case, but it is too stiff and difficult to open. Hello, customer. This is GVG STORE. Thank you for your valuable review. :) You summarized the important points very well. The fact that it is waterproof enough to be used while diving seems to be an attractive purchasing point for other customers as well! I also expect that the stiffness of the case will decrease as it gets used. Thank you very much for your order. We appreciate your continued interest and support in our GVG STORE! Wishing you many blessings in the new year 2024! Thank you! :)
