Make your broken arrow shafts into cool arrow pens with Bohning's Arrow Pen Ferrules. They work with stick pens similar to PaperMate® 1.0mm and standard size carbon arrows - just take the "guts" out of the stick pen, slide on the Arrow Pen Ferrule, then insert them into the arrow shaft (making sure there are no jagged carbon shaft pieces of course). No tape or glue necessary. Sold in 100 packs. Proudly manufactured at the Bohning factory in Lake City, Michigan, United States.
