These and used to keep food from spiling and used to keep folders closed or keep 2 or 5 folders together temporarily for projects. Perfect for my use.

Strong grip for keeping packages closed. Way better than plastic ones where the joints tend to break near the spring. My only comment would be to be careful of the sharp metal edge on the inner surface. It could potentially cause a paper cut-like injury if fingertip angles inward.

strong clamp force

Closes a bag with a firm grip. It is made entirely of metal, and so there is no risk of the clip breaking apart like the plastic ones.

Very sturdy. Will last a lifetime. But they are heavy.

Durable little clips. So far so good compared to some plastic clips which have easily broken in the past.
