The containers are leak proof, microwave safe, dishwasher safe, freezer safe and BPA free. They come in five sizes - 600ml, 1-litre, 1.2-litre, 1.4-litre, 1.5-lire - and there’s also a vacuum pump, which is free with five container credits.
You need to have a Fly Buys card to redeem, and the promotion starts on Wednesday.
And once you have enough container credits for the size of container you’d like - you can redeem and collect! It’s as simple as that!
