Around the waist, a soft lined band adjusts to a perfect fit as two thin straps reach around to loop under each butt cheek. Simply tug the strap ends to adjust sizing. Around front, set perfectly mid-yoke, one of three sturdy metal O-rings secures a dildo or vibe of choice into place - the ring snaps on and off for quick toy attachment and any possible penetrator switch-ups. The included rings are 2"/5cm, 1.75"/4.5cm and 1.5"/3.75cm. Spot clean as needed.
