Gale Force 9 have updated their Massive Wounds token set.
From their website:
Gale Force Nine has upgraded our classic Massive Wounds set with all new full-color tokens. These bright red tokens really stand out on the tabletop and will help you keep track of multi-wound models as they take damage during battle. The first three wounds are blood drop shaped, while wounds four (4) through six (6) are increasing larger pools of blood. These wound markers can be used in all manner of miniature battle games and role-playing games.
