Aderia Retro Mini Letter Set / RYU-RYU

A mini letter set built around the iconic glassware designs of Aderia Retro, the Showa-era revival collection that became a cult hit in Japan. Each set includes die-cut writing paper shaped like the glasses, envelopes modeled after the original packaging boxes, sealing stickers with each pattern’s logo mark, and a paper case printed with the design inside and out.
