Inner circumference: Approximately 17cm. These are imported, no-brand items. They are made with stretchy elastic thread, making them easy to put on and take off. The knots are reinforced with glue, but please be careful as they may break if pulled too hard. Discounts available for multiple purchases! ¥150 off per item for the second item onwards. If you would like to purchase multiple items, please comment with the number in the product name. I will create a dedicated listing for you. I have many other bracelets that I haven't listed yet! Feel free to ask any questions. Shipping will be via anonymous Mercari delivery. #CactusBracelet #Cactus17cmBracelet #CactusMensBracelet #CactusUnisexBracelet #CactusBohemianBracelet #CactusLargeBeadBracelet #CactusWoodBeadBracelet #MensBracelet #Unisex #Unisex #BeadBracelet #WoodBeadBracelet #Ethnic #Exotic #Folklore #Bohemian #Tribal
