You can stamp on uncoated paper, postcard, photocopy paper, sketchbook, note book, etc with this 1" x 1" Ink Pad. Drying time would be 10 to 15 minutes on uncoated papers but this varies based on weight or type of paper, humidity, etc. It is very suitable for embossing since it dries slowly. (recommended to use transparent embossing powder). Acid free, non toxic, fade resistant, traditional water based archival pigment ink.
