A pair of personalised split sound wave key rings with any song of your choice for a couple\'s favourite songs. We create an exact physical soundwave model of your song using steel, which we then infuse with plastic in order to help construct these highly detailed shapes, whilst still retaining the look, feel and smell of this material without any sharp edges. Made at our studios in London, each piece is polished/sanded by hand and as every song produces a different soundwave this helps us to create something unique for every customer that is ideal for music fans, homemakers and creatives. All orders come packaged in the gift box pictured.
