Club Ghoul O Negative 4oz Refill

O Negative is a 4 oz refill of red, oil-based dye ink formulated with staining performance in mind. Its deep red color gives your refillable markers and mops a different option from the more traditional blacks, blues, and violets.

O Negative is dye-based and best suited for indoor applications, according to Club Ghoul. The highly staining formula means extra care should be taken when filling markers, handling the bottle, and working around surfaces you don't want permanently stained.

Pair it with a compatible refillable mop or marker and keep your setup loaded.
