This is an opaque parabolic hollowed blade tip that has been designed to fit a mid grade blade tube that has an outer dimension of 25.4mm (1″) and a wall thickness of 1.8mm (0.07″). It comes with a reflective ring base sticker that helps create an evenly lit blade and blade tip when used with an in-hilt LED saber. If this blade tip is used to build a Neo blade, the reflective ring base sticker needs to be removed first.
