Using this strap-on is easy. First, adjust the leather waistband to fit your size up to 48. The adjustable leather harness ensures a secure and comfortable fit. Then, attach the 8-inch jelly dong to the metal O - ring. When using, make sure to clean the jelly dong before and after each use with a mild soap and warm water. Store it in a cool, dry place away from direct sunlight to keep it in good condition. Also, since it's phthalate - free, you don't have to worry about harmful chemicals, but always use it gently to avoid any damage.
