Generally, I fold the edge and use a regular clip. These work so, they are OK but, it's adds an extra item to store in one of the cupboard drawers. If the container is not suitable to smaller clip, one pack .will last for a long time because you can reuse them several time..

These are so handy to have on-hand. They work as expected.

Good sealing clips.

great value

These clips work fine

Works, same quality as dollar store
