GMK Mutagen has been released! A caustic love letter to all things chemical and dripping with danger. Fair warning though... From the slimy translucency, grimy black inclusions, and glow-in-the-dark pigments, this set is alarmingly contagious.
Increase your toxicity with the metamorphic novelties of the Outbreak kit, keep it in check with the reversed white-accent Containment kit, or throw caution to wind and collide them into a poisonous concoction of your own making.
You might think this oobleck is too hazardous to handle, and you'd be right! But I triple-dog dare you to do it anyway.
