Especially for large area markings, this water-based, odorless ink is non-intrusive. The ink without a capsule prevents quick drying, and the chisel tip allows for a line width of approximately 3-10 mm (refillable with ink). The presentation marker TZ 48 is particularly well-suited for flip charts and other paper surfaces. It has a white barrel color, a minimum line width of 3 mm, a maximum line width of 10 mm, and a chisel tip. The color is black, and it is not waterproof.
