This is the ink you need to create heat embossed images or watermarks.  The slow drying, clear translucent ink produces a stamped image slightly darker than the paper color creating a watermark effect that can be used for a tone-on-tone effect on colored paper or as a resist. You can also use it on vellum for a lustrous look.  Acid-free, water-based and non-toxic. 
Ink pad is currently out of stock.  Refill bottle is 0.5 fl oz (15 ml).
