After you insert a clothespin in the back you attach a strip of magnetic tape to the back. It becomes a refrigerator magnet to clip a piece of childrens art work or appointment card or any number of things. You can purchase magnetic tape on a roll or you can cut up (in strips) magnetized business cards and hot glue to the peg. Sometimes these magnetic cards can be picked up from the doctors/dentists office or the pizza delivery.

Good question. For those of us with grandkids who make us adorable art work, we use a lot of the pegs. ;)

They can also be used to keep your chip or snack bags closed. By adding the magnet, you can get double use! My daughter likes the ones with magnets as she "stores" them on her ref. for use with the bags. I put some hot glue inside the pocket for the part of the clip that goes in there as well as on the back side of the clip to be sure the felt stayed close to the clip. They are GREAT! (Here we call them clothes pins instead of pegs..most of the time)

I use them to clip all my packets that has been opened and does not have a closure when I don' want anymore bottles and tins in my cupboards. These are lovely with multiple use.

Good question!!!!!!! I have been wondering myself. Now I know. Hugs Marg
