CoveBox

CoveBox is a monthly snail mail envelope with a new theme each time. The September 2026 edition, Cozy Fall Vibes, brought a themed postcard, a screen-free pencil activity such as a crossword or word scramble, two themed stickers and an art print.

Each edition is $8 with US delivery or $11 internationally, and you can buy a single month or subscribe so it renews automatically. Every edition has a sign-up deadline; for September it was the 15th, with mail sent on the 22nd.

A light, affordable pick for anyone who likes small seasonal surprises and puzzles.
