Once you have the yellowbox app, simply find a box on the map and hit Open to start your booking.
Use the transfer button above the booking panel to send your booking to another user!
They will receive a text message with instructions to download the yellowbox app and will be able to accept the booking transfer once they sign in.
For locations with a keypad, e.g. at the beach or swimming pool, you can set a 4-digit code in the app, allowing you to store your phone and unlock your yellowbox using your 4-digit code to retrieve your items.
