These magnets, approximately 1.5cm in diameter, come in a set of 5 and are perfect for convenient storage. I purchased them to use with PP bands, but the repelling force of the bands was too strong, causing the magnets to detach easily, so I am offering them for sale. (Only one of the nickel-side magnets has been opened once.) They can be easily attached with pliers, making them suitable for making fabric bags or adding to your existing tote bags. - Model: SUN14-123 - Quantity: Set of 5 - Size: Approximately 1.5cm in diameter - Country of Manufacture: China Thank you for looking.
