Medium Square 3.t Ovenware

Cooked pork beautifully. Cake did sink in the centre but was easy and delicious. Would like another ovenware a little larger next purchase. Very handy to collapse container for refrigerator or when storing. Love it.

easy to clean

I have only had an opportunity to cook a roast in this Medium Square 2.5L ovenware Flatstack. The roast sat on the bottom had quartered potato and carrot sitting on top and I added some male syrup to this combo before cooking. The roast was good, and I'm not a very meaty person, so were the vegies. I washed the container and when dry put the remaining roast into the container. It has kept well and I must say I don't like Flatstacks.... I love them. Looking forward to using this new Flatstack on the BBQ whilst travelling.

Space saver

I have these containers and I love them, if I have a small amount left over after a meal I put it in one of the smallest ones and collapse it, you have a choice of different sizes for large amounts or smaller amounts.

The item for storage purposes is good, but doesn’t have a solid seal so dies leak some when traveling. Mostly a problem when taking left overs for lunch.

Impressed, these are great 👍

Customer Service is LESS THAN DESIRABLE

I received multiple sets. I did the light wash as insert instructed and the large green top no longer snaps to the large green bottom. I've sent 2 emails and called whenever I could--the time difference makes it hard with my schedule--and I've gotten nowhere. Aside from not being able to use the large green stack, I'm happy with the other stacks. I've kept my larger containers from the other brand to be safe, because I'm just a bit nervous.

Love 'em!!

I love everything FlatStacks makes! I'm especially glad to have these jumbo ones as we approach Thanksgiving!

Disappointing

My husband used these in the top shelf with at least a 50mm gap from the top and the dish is destroyed. I certainly wouldn't use it on a BBQ as suggested if this is what it does in an oven.
