Brilliance Graphite Black Ink Pad
will give you a gorgeous impression with your stamps.

This Tsukineko Brilliance Ink Pad is a great option for creating art in a different way. The pad can be used with stamps as a traditional ink pad or on its own as a paint. It has a unique design where the pad sticks out from the case so you can experiment with direct to paper techniques and hold the stamp at any angle.
You can use the ink on uncoated and coated paper types plus photos, leather and cellophane, unpainted wood, polymer clay, plastic and terracotta.
