DIY Ink Activated Postcard x Nouto

Magical! Featured as samples at my booth at the 2023 International SF Pen Show, on surface these cards appear completely blank — but look closer and you'll see intricate traces of a design. Once activated by fountain pen ink and water based ink, the card displays beautiful pigment and the lovely design on the card. 

• set of five (5) postcards
• 3 7/8 X 5 7/8 in

made in japan

These Nuritakurie cards are by high quality Japanese stationery company Nouto. The company came up with this innovative concept to allow non-wasteful use of the ink bottle and to share your favorite fountain pen colors with fiends through exchange of postcards.
