These strong magnets are used to secure items to the table of the Pragnant stamping machine.
If the material is thin they can be used on top of the material, or in the case of a book cover they can be used on the left and right sides to lock the cover into place.
Quite an essential accessory for this machine. Magnets are available in two sizes: 3/4" by either 1-1/4" or 5" in length. (20mm x 30 or 120mm in length)
