Compare suction bases, removable mounts and harness sets
Check the attachment before buying a replacement or matching an existing harness.
Separate a suction-style base from a removable mount
The Real Rock and Together Toys listings describe suction bases. The UltraSkyn listing also names a removable base and a specific attachment system. A photo of the bottom and a listing for the exact variant can help you confirm what is included. For more base shapes, see the suction cup dildo guide.
Check the hardware that comes in the box
The Master Series listing includes three rings and gives the waist range. If you already own a harness, check its instructions for the compatible base shape and ring size. A shaft width alone does not establish whether the base will fit securely.
