The advantage is that the exterior looks simple and sturdy... Also, the part where the number lock locks is unique. The disadvantage is that the structure is difficult to open and close, and the interior does not look sturdy, so I think you will have to use it to find out. Despite the disadvantages, the advantages mentioned above outweigh the disadvantages. It's a cool product that can be offset...

I wanted to pack something like this with a company bag, but it's great

The design is pretty and the finish is good. However, if you use the USB A port as the charging terminal, only 1.5W (4.9V, 0.33A) speed comes out, and the C port does not work at all, probably due to poor compatibility. If you just say no, the rest is fine.
