Sadie's Stickers Snail Mail Club

Sadie's Stickers mails a themed envelope each month with a full sticker sheet, a waterproof vinyl decal, a blank 4x6 postcard to send or journal with, and a letter in mini zine form that may hold an activity, journal prompts or a note from Sadie. Recent themes have ranged widely, from koi and Japanese motifs to seasonal designs.

The club is $9.75 a month and bills on the date you first signed up. Letters travel by USPS with a stamp and no tracking; US shipping is free, while international members pay for postage at checkout. It is separate from the shop's mystery subscription, and past editions can be bought individually.

Good for planner and journal fans who go through stickers quickly.
