Fridge Mate 1.5L
Okay, don't start. I do know you can buy something similar in the pound shop. But can I just point out that your Tupperware Fridge Mate set is a super premium quality product, comes in a stylish midnight blue, and comes with a 10-year guarantee.
The deep blue colour doesn't stop you checking the contents: there are transparent windows on each side.
