Specifications of Uni-Paint:
The Uni-Paint Brand of oil-Based Permanent Paint Markers, from Japan were the first valve-controlled markers to be sold in the US. Current owners of Arro-Mark® George and Stephanie Pappageorge were the first company to import these pens to the USA. Shortly after that, they designed and manufactured their own valve controlled marking pens which surpassed the use of Uni-Paint for Industrial use. Uni Paint is still supplied by Arro-Mark.
