Lovely colours and good range of sizes. Just bought a 2nd lot to give to my daughter in law for her birthday. My son's family does a lot of travelling for holidays and these will be very handy.

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.

Love that the lid colours match the basees

Such great products!!

I'm happy with the ovenware set. I like the gloves but they are for very large hands and so I find them hard to use.
