These pretty Butterfly design erasers are a full, regular sized eraser measuring approximately 2.5cm in diameter.These erasers can be embedded into a single bar of soap, or tucked into gift packs or used for party favours, or teachers prizes. Like all erasers that are embedded into soap, they can be a little rough on the skin during day to day use. We recommend the eraser is embedded into a single layer of clear soap, with an overpour of a contrasting colour to match the eraser.Not suitable for children under 5 years of age - possible choking hazard due to size.
