The MTN Montana Colors Technical Marker range is a series of fine line markers. Designed primarily for use on paper surfaces, these markers are filled with highly pigmented water based ink. Highly opaque & quick drying, the ink will cover most types of colour without any show through. The markers are ideal for sketching, drawing, outlining and writing too. Technically, these markers really excel with their precision sized tips. Through the range you have incremental sizes from 01.mm to 1.0mm, a brush tip and a calligraphy tip. The 1.0mm also comes in silver and gold for fine metallic details.
