Wow Flat stacks 👍

I ordered these after seeing the ad on Facebook. Love the fact they are silicone plus can be pushed flat for storage. I love the colour and the product so much I’ve already thrown all my old plastic away and ordered a second set. My plastic drawer is looking fabulous thank you 😊

Super style

We love the Flat Stacks range. We have just replaced all of our plastics and Tuxxxxware and have freed up valuable cupboard storage space. Flat Stacks have solved the too big too small issue of regular plastics. We have even set aside a specific set for camping. Great product range, thank you Flat Stacks.

It’s impossible to offer a review when I still haven’t received my order and your customer service tells me that can’t even find a record of my order.

Convenient

Only used a couple so far, but even good to take out when dining for left overs, as compacts well in bag, to save waste.

Love them and going to replace all my Tupperware 😉

Rectangle Value Pack

Very happy with this set, they stack perfectly in the van. Looking forward to having a container for everything while we travel.
