Plenty of containers all in one, easy to get to, drawer

There's nothing worse than bending down to a low cupboard trying to find the right container for the job. I ended up emptying the whole cupboard to find one. Now it's all in one drawer & easy to see them all. Plus they silicone not plastic. I love these flat stacks & the packs are great value to boot. Highly recommend.
