We also thought a lot about the details. To solve the problem that plastic cases are easy to be damaged, we use more durable materials, and now our cases are more durable. Besides, other brands use non-woven fabrics, but we offers 100% cotton fabric with higher cost and better quality. The cases and accessories are marked with calibers so that you can find the one you need more quickly and put back more conveniently. All accessories are of higher quality, just to give you a better use experience
