The Speed Shift Erection Ring gives you a choice of fit instead of locking you into one fixed size. Its black design combines multiple size options with adjustments you can make while wearing it, so you can fine-tune the fit during use. A quick-release design keeps changing or removing the ring straightforward, which can make it an approachable option if you are new to erection rings. You can select a size for your own use or adjust your choice when a friend visits. 17 size tabs: Choose from 17 options to find a fit that suits your preference. Two-inch increments: The sizing steps give you a range of adjustments between size options. Quick-release tab: Release the ring when you want to remove it or change the selected tab. Ball rope and guide: Use these parts to adjust the ring while it is in use. Consider the different tab sizes as you decide which fit feels right for your use. The adjustable design lets you make that choice without committing to a single fixed size, whether you are trying an erection ring for the first time or selecting an option to share.
