Fibre tipped pens which use washable inks which mean they can be removed from most textiles. The quality fibre tipped pens are dry safe so the cap can be left off for days without drying up. Class Pack of 100 or Pack of 10. Washable pens are water-based and ink may wash out of clothes.
Water soluble pens mean that the ink is water-resistant after drying and will not wash out easily.
