【CAMEO】SMART CUBE aqua 's Japan Review

I purchased this following the pink and blue.
The colors are still beautiful.
I am concerned about the durability of the open/close part, but the two I bought earlier have been in use for 2 months and so far I have had no problems with them.
I like that there are no bumps, but it is true that it is bulky, so I guess this is a matter of personal preference...
