Easy to print. 1 pellet takes about 2 min. Just a basic 6mm pellet for airsoft guns. Lost all your airsoft pellets? Print some! Comes with 1 pack, 50 pack, and 100 pack.
NOTE: These work just as well as commercial pellets. I test fired both from the same gun and position, and they basically hit around the same spot. (Including the displacement in my hand position after reloading using a handgun)
