Based on the mightily uplifting little book, Ishi: Simple Tips from a Solid Friend and its adorable Instagram account, @ishitherock, Ishi Postcards is a set of 30 postcards to send to someone in need of a boost. Designed to be multi-purpose, these cards can be used for everything from birthday greetings to sympathy notes, or just to let someone know that you’re rooting for them. Ishi reminds recipients to take comfort in inner peace and embrace the joy of life’s smaller celebrations.
