4 pieces, pads measure 1.25 x 1.75inch (3.12 cm x 4.45 cm). Set includes Black Marble, Bubblegum Pink, Calypso Teal and Dirty Martini. Mini Dylusions Archival Ink Pads are waterproof acid free dye inks featuring the classic Dylusions color palette in the same fade resistant formula used in Ranger Archival Ink. Archival Inks are permanent on many surfaces providing long lasting detailed stamping results that will not bleed when used with waterbased inks, markers, acrylic paint and watercolors. Ink Pads can easily be reinked with coordinating Dylusions Archival Ink Reinkers. The small size makes these ideal for craft projects on the go and they can be stored in the Mini Archival Ink Storage Tin.
