The sperm keyrings are available in a wide range of colours, as shown, including Glow in the Dark and Thermochromic Purple.
( Bespoke colours are available subject to minimum quantities).
With the Thermochromic Purple Sperm Keyring, the special pigment causes the sperm to change colour when there is a change in temperature.
We make the sperms in three sizes:
Small, Medium and Large
and can offer the differing fittings of
Split Ring, Keyring ( Keychain) or Ad-Loop.
An alternative to the insert is the Ad-Loop which can be branded with
colours and information to suit your campaign.
