50cal foam ball (100 balls pack)

This is a 100-ball pack of 50cal foam balls sized specifically for the Monkee Mods Firefly and the MM x Walcom S7 Firefly unit, so if you're running either of those shell-firing blasters, this is your restock ammo rather than a universal round that fires everything. A pack this size is meant to get you through a decent number of rounds before you need to reorder.

One thing worth flagging: the shell shown in the product photo is there purely for illustration purposes to show scale and how the balls sit inside it — the shell itself is not included in this listing, you're buying the 100 foam balls only. If you already own a Firefly or S7 Firefly unit and are just topping up ammo, this is the pack to grab.
