First of all, it is strong and has a height, it is useful for storage. It is surprisingly convenient for the inner lid type L, even if you do not remove it, it is possible to put in and out the lower tool. The double-buckle opening is excellent.
The size is just right, and it is likely to come in various ways. You can open from both sides when opening and you can also remove the lid. I just bought it, so I do not know the durability, but the price is also cheap, it seems simple and easy to use.
