Secret Weapon Miniatures have received stock of their 28mm Bio Sword conversion parts.
From their website:
The new Bio Sword conversion bits are live, in stock and shipping immediately.
The swords come in two sizes and each has a distinct left and right hand sculpt. The sculpts feature distinct fingers, teeth, a bone spike and gaps between the fingers and the organic blade.
The new Oni Mask Head Swaps will also be available to pre-order later this week.
