Description

The IM-101 Mighty Marker® Blackout Pen - Fine is used to mark and correct imperfections in window tinting application and other forms of transparent film. The extra-fine 1.0mm bullet tip of this translucent black pen allows detailed touch-ups for covering small line-trimming mistakes in shaded film to keep out the light.

This pen contains a specially formulated, water-resistant and UV-resistant alcohol-based ink that effectively blocks light transmission and replicates the shaded film's surface. Ideal for small scratches and cut marks on film, pinholes, nicks, and minor cut marks on window tinting, transparent film, and camera film. Ink dries in less than a minute. Durable aluminum barrel, valve-controlled, rated for use from -20°F to 130°F (-29°C to 55°C).

A necessary tool for auto aftermarket work, window tint shops, and autobody & towing operations doing precision film touch-up and repair.

Manufactured in the USA by Arro-Mark®, 70+ years of industrial marking craftsmanship.
