This adorable hedgehog keyring is made from 2 layers of Bullseye Tekta clear glass and has a single copper hedgehog sandwiched inbetween the 2 layers of Bullseye Tekta. The keyring measures approximately 4 cm x 6 cm (including the metal silver tone swivel clip makes the total length of the keyring approximately 11 cm). No two hedgehog keyrings are identical as depending on the texture of the copper foil when it is cut out – ie if it remains smooth after firing it will keep its red coppery colour but if crinkled a little will turn an amazing shade of blue – sometimes of course you will get a combination of both blue and red! This therefore makes each hedgehog keyring unique.
