This is the best storage box/bin that I have ever had or seen. It is made of very durable materials. The seal is excellent, and with the number of handle/clamps the seal is exceptional. I like the clear color which makes the contents view able. I have used bins for everything from dog food to clothing, photos, art supplies, and keepsakes and now I have found the best one by far. I like that they are stackable and I will be purchasing several more and some of the smaller versions. You will not be disappointed with these box/bins.
