This is a set of 4. Please inquire about individual sales. These were obtained many years ago and were attached to my refrigerator at home. The magnet has come off of one of them due to deterioration. They will be shipped as they are. Size: Approximately 3-3.5 cm Due to the material of the product, they feel somewhat sticky to the touch. Please understand this before purchasing. They will be shipped in simple packaging using recycled materials. Shipping is generally closed on weekends and holidays. Thank you for your understanding.
