This 10mm diameter core is 120 cm long and solid glass-fibre. This makes for the strong and flexible core ideal for building your own spears and two-handed weapons in foam and latex. Take your time to clean and sand the core before use; the glue will grip a sanded core better and improve the durability of your new favourite weapon. The series of Epic Armoury DIY articles equips you to make your dreams of a foam and latex design come to life, while letting you benefit from the quality materials used in an Epic Armoury Weapon.
