JJC MC-10D Water-Resistant Memory Card & Cellphone SIM Card Case Protector for 2 SD + 2 Micro SD + 2 SIM + 2 Micro SIM + 2 Nano SIM Cards Storage Dark

This is very compact was very surprised about the size. Only issue I have is that it’s a little thick. Actually was looking for something real thin.

Great buy. Durable case, can hold all my SIM adapters snuggly. Great for someone who likes to swap phones A lot, or someone who does A lot of unlocking of phones.
