For complete arm control the Strict Leather Bondage Sleeves are the solution. Encase theirs arms in the soft garment leather sleeves. Enjoy the inner flap that will fill the space between the laces making them not only functional and secure but very comfortable. Use the 3 D-rings that are attached to the wide leather straps for securing the arms together or to other objects. The options are limited only to the imagination. Opera Gloves measure 27 inches in total length and can fit a wide variety of arm sizes by simply adjusting the lacing. Sizes: Small/Medium: Better fit for most women. Medium/Large: Better fit for most men.
