This is a lightweight & durable wristband made from polyester elastic. These will easily stretch an additional 3-4 inches so you can easily get them on & off. The wristbands are 0.5 inches tall. Reversible - easily flip it over on your wrist. Size Guide: Best is to use a flexible measuring tape & measure your wrist. This will allow you to have it made as tight or loose as you prefer to wear it. If you have a size that is different than the ones I have listed, then just send me a message & I can make it to that size. These are unisex - made for both men & women. The elastic does contain latex. Handmade in the USA. These are made to order but we try to get all orders out in 24 hours. Alexis Danielle Hill Reversible Bracelet Wristband
