About

One Envelope

Lighter than a handwritten letter, more thoughtful than a quick message. Type your words on a mechanical typewriter, add a stamp, and seal the envelope. Send it as a link, and the recipient opens it like tearing open an envelope. If they have the app, it stays in their inbox. You can also set an opening day, so it opens on a birthday or a holiday morning. Links work anywhere in the world. Only the first device that opens a link can open it again, and you can recall a letter at any time. When you'd like it on paper, we can print it and send it by post. Physical letters can only be sent to addresses in Korea. We hand them to Korea Post within 2 business days after payment, and delivery time depends on the post office. - Type on a typewriter with Korean and English keyboards - Key sounds, a return lever, and a bell at the end of the line - Decorative stamps inspired by Korean folk art - Send a link right away, or keep it sealed until a date you choose - Received letters are kept in your app inbox - When you reply, the recipient's name is filled in for you - Physical letters to addresses in Korea by standard or tracked mail Made by Teo Studio (Taeyoung Park) Contact: info@teostudio.org
