The same photo keyring for weddings and the photographs from the day.
The same photo keyring for anniversaries and milestone years together.
The full keyring range in heart-shaped acrylic and rectangular styrene, printed both sides.
A keyring carrying the scan image, handed to a parent or a sibling, does the announcing and leaves them with something afterwards. Cheap enough to make several for the whole family.
A grandparent who is not on a phone gallery still carries keys. It is the most reliable way to make sure a photograph of a new grandchild is actually with them rather than in an account they do not check.
For a parent going back after leave, a keyring on the office lanyard or the car keys is a small, unfussy thing that does not need explaining to anyone.
The acrylic heart, which marks too easily for daily keys, is well suited to a keepsake box alongside the hospital band and the first scan printout.
