Here are 4 refill packs for the ERTL Outddor Sportsman series shooting toys from 2008. You get 3 six packs of blowdarts that work with their rapid fire dart gun or blow gun. You also get a 5 pack of foam balls that work with their bow and crossbow sets. I believe the foam balls also worked in a shotgun that they produced. All 4 sealed packs for one lot. These refill packs are scarce today.
