Furukawa Paper Coffee Mug Mini Letter Set is made with Mino washi paper, a traditional Japanese paper with over 1000 year history. This set comes with 4 mug & letter paper sets, 3 envelopes and 3 sealing stickers. The letter paper sheet is pre-cut to look like steam rising out of a hot drink in the mug. Before sealing it into the envelope, you slip the letter paper into a slit cut into the mug so that your friend receiving the letter will lift the "steam" out of the cup to reveal your message.
