The 21st used to be when you got the “key of the door”. These days it’s usually a celebration of finishing uni, a first job or a first flat — and a good excuse for a present that feels properly grown-up.
A star for their 21st
Name a real star. A heartfelt gift they’ll cherish forever. Our sister company, The Star Naming Co., dedicates a real catalogued star to their name, with a dated certificate, a sky chart and a live viewer to find it. It’s symbolic rather than official — a memorable, personal present that’s easy to send if you can’t be at the party.

The “key of the door”, reimagined
A decorative key is a lovely nod to tradition — but pair it with something real: a key ring for their first flat, or a contribution towards a deposit or first month’s rent, tucked inside a card with the key.
