Charm back for 4 inch jumbo paperclips

Use this as a base to attach cabochons, gemstones, and other charms and decorations to the top of 4 inch paperclips. Lay the base down, insert the paperclip, and glue the adornment to the top. 

There are two versions with varying thicknesses of the back wall. Either will work with 4 inch paperclips. For other size paperclips, resize as needed.
