Kastaplast K4 Glow Sten

Kastaplast’s K4 Glow plastic is the same grippy, flexible blend as standard K4 but with added glow-in-the-dark capability. This hybrid plastic balances comfort and durability, offering a soft, slightly gummy feel with reliable grip. It maintains consistent flight as it wears and even floats in water, making it ideal for casual play or evening rounds.
