A part of the review has been auto-translated.
I had ordered these previously and had to get more. They are very convenient, good size, like the flip-up lid and most of all they keep my spices dry. Granted it's not an airtight seal but with me using salt, pepper and sugar often, it keeps dry enough that I don't have to worry about clumping. Ordered more to use with my other dry goods, i.e. cornstarch, flour. sesame seeds. The only thing I would suggest would be that making it a stack-able. Otherwise, I recommend you try this out.
I love these so much that I ordered more. The fact that when closed it feels airtight until I flip it open. Labeled each one using my label-maker. The spoons that it came with fits nicely although it doesn't adhere to any measurement portion, i.e. 1/4 teaspoon, 1/8 teaspoon, etc. But I would recommend since my kitchen counter looks much more organized in my messy kitchen.
