Puppets War will scratch your back if you scratch theirs… though I wouldn’t suggest using these new Hellclaws for that.
From the website:
Set contains 10 Hellclaw arms (5 right and 5 left), parts are compatible with barbarian and striker armours, and also have 3x1mm magnet type holes enabling if using magnets to easy mount and dismount arms. Model is designed to fit 28mm “heroic” tabletop wargames scale (fits perfectly to striker and barbarian armour) supplied unassembled and unpainted. Designed and sculpted by Puppetswar Art Team.
