Flat stacks rock

I love my new little family of flat stacks. My draw is organised and have another draw free because of my new little babies being so small.

Boxing Day Special > 2 x Square Sets + FREE Round Set

Really great

Quick delivery. These are airtight, and can flatten down as the contents get less. Then fully flat to stack on the cupboard. FANTASTIC!! Now to get to throw out the older storage containers.

Best storage containers ever!

I love how easy it is to store Flat Stacks because of the ability to squash them flat and also their lids can be pushed down to closely cover food items. This means less air so food lasts longer, while taking up less room in the fridge.

Boxing Day Special

Absolutely love my NEW sets. The colours are so beautiful. I used all my sets (purchased earlier in the year) for Christmas Day 2020 and all my family were totally in love with them. The table looked so bright and organised. Packing up leftovers was a breeze.
Easy to order and very fast delivery. Thank you thank you thank you for my gift $20 off my next order. I will be ordering some more soon for family.
