I love these OXO POP Containers...I have several of the round ones, but I really love this big square one. I will say that the POP lid on this square one works WAYYYY better than the lids on the round ones. When this one is engaged, I cant take the top off without a struggle...the round ones just slid right off, even when the POP is engaged. I keep this one on the counter as a cookie jar, and it works great for keeping cookies fresh!
