The envelope (: kirjekuori) is an item which appears on the player's garage table once an order has been placed through the parts catalog, or next to the mail box once the order for the computer has been signed. The envelope must then be taken to the post box outside of Teimo's shop, on the right-hand side of the entrance door. Dropping the envelope into the box should make it disappear, indicating that the order has been mailed.
Teimo will call the player after 5000 (That is 83 minutes) seconds of waiting to let them know that the package has arrived. In order to receive the package, simply click the post order note on Teimo's counter to make a payment,
