About These Strips For the DIY band maker, this is the raw material — precision die-cut SimpleShot Premium Black latex in clean strips, ready to build into your own bandsets. Pick the style that matches your ammo, cut each strip to your draw length, and pair it with a pouch (sold separately) for a setup that's entirely your own. The same latex, your build. Every strip is steel-rule die-cut from the Premium Black latex — our best yet — that goes into every SimpleShot bandset, so your homemade bands shoot consistent and last. Strips come in packs of 12, each 270mm long. Built for round ammo — not rocks or stones.
