Javelin heads made from tough acrylic which withstands being thrown at wood or other soft material.
2 slightly different heads in each moulding.
Made after original metal forms.
Delivered in cream-coloured soft acrylic plastic.
Not cheap, but 3d printing eliminates moulding bubbles and guarantees quality and strength.
When painted with metallic acrylic paints - use an undercoating layer also - look very realistic.
Can withstand light combat use but metal weapons will eventually damage them.
Set them on wooden shafts for use.
