1.

Empty out your last drops of oat/nut milk.

2.

Fold out the bottoms and squish the container flat.

3.

Cut container across the middle or to match the size of storage container you require.

4.

Wash the container with your normal washing up and leave to dry.

5.

Store flat so it doesn't take up much space.

6.

When needed, fold back to shape and fill with food for freezing.

7.

These don't wear incredibly well, so we only suggest using them once or twice - and do not defrost in the microwave.

8.

When finished, wash and recycle in your Harborough Blue bin.
