Zen Frog Mail Club

Zen Frog's monthly envelope follows a theme of whimsy and wonder: nature scenes, cozy moments and small magical creatures. Each one holds a 5x7 art print, a mini calendar, three stickers, a bookmark and a letter, all in a custom envelope. The September 2026 print was a piebald deer.

Membership is $10 a month in the US or $12 internationally, with shipping included. Mail goes out at the start of the month; sign up at least a day before the 1st to receive that month's envelope. Letters are stamped, so there is no tracking, and past prints can be bought singly in the shop.

A calm, colorful choice for nature lovers.
