This is the perfect flour jar! It’s 1 gallon in size. I bought 2, and wish I’d gotten more! They have a seal around the lid!!! This is one of the only ones I’ve found that seals! Im using one for flour and the other for my laundry pods. They are back ordered now, but I’m on the list for more. Will be ordering more for sugar, coffee, rice and stevia and maybe a couple more for who knows what else! Love, love, love them!
