These are for .166 arrows the heads are size B or #276. I have 2 full packages of heads/inserts/collars I super glued one head closed to use as practice and hot melted two of the inserts which are still in great fully functional condition. The rest of everything shown is brand new. So 5 brand new broadheads with all included bands/plugs plus practice head. 6 inserts/collars plus a package of 3 additional inserts. And 6 brand new field points. This cost me over $200 new I’ll let it go for $125 shipped PayPal F&F or cover fees, Venmo, Apple… thanks!
