Flat Stacks

We love Flat Stacks containers - they are versatile, durable, leakproof, and easy to store. We purchased a set originally at a Christmas show and sale event, and got a lot of use out of them. We wish we could find them in stores for purchase.

best bowls

love these. I would buy them again. Highly recommended

Love them! They say what you said they would! I stored some Brussels sprouts in one of them & no odor or stain!

Great Product

They are space saving as stated. the large containers allows you to store a complete 9x13 casserole in them. Wait then you can collapse them making more stackable space in the refrigerator
