The Riccio clip-on glass marker is a small accessory that attaches to the rim of the glass to identify it and distinguish it from the others. The shape resembles a stylized hedgehog, with a rounded body and a side clip that fastens to the glass. Useful for tables with several people, parties and social occasions, it helps to recognise one's own glass and to reduce accidental swapping. It measures 3 cm in its largest dimension
