I already had some flat stacks but needed more. I love flat stacks especially the ovenware because I can do no mess cooking. Im saving up to buy the larger cookware so I can bake cakes and larger quantities of meat. I love my flat stacks

Love how well they fit in my tiny draws

Absolutely gorgeous, will be buying more - happy to retire some old containers even though theyre still functional they don’t bring you joy like these flat stacks do.

Ordered a second set

No more swearing at my container storage drawer!!! I love the quality and the space savings the most. Thank you.

Love them

Nice collapsible storage

But a bit pricey. It is well made. Closes securely and the side walls are thicker than most other brands. Recommend!
