"OTR .084 FLOWPEN stands for an extremely even, fast and drippy ink flow and a distinct super permanent script. Flow Control Pump Technologies is a unique marker system with a very smooth moving valve. Easily controlled by applied pressure to the tip, either juicy tags with long drips or sweeping clean letters emerge. The OTR .984 FLOWPEN INK is a high glossy ink that is luminous and slightly transparent on smooth materials and covers colorfast on porous, absorbent surfaces."
