The Amicus Chastity Cage available at malechastitynow.com is a semi custom cage available in two cage lengths. The length options are 1.75" and 2.25". The internal cage diameter is 1.25". The design is simple and elegant. Purchasing Experience Male Chastity Now is a great name for the business, because you get the products very quickly and in my opinion at an amazing value. The customer service provided by Mark at Male Chastity Now is as good as it gets. Very responsive and helpful. Including offering custom sizing options not available on the site. Build Quality The overall quality of the 316l stainless steel cage is excellent. The finish is very smooth and polished. You can tell they are made by hand. The security screw lock is simple and effective. Does not loosen and the unique head would be hard to find, never seen one quite like it. For $160 us dollars it offers some of the best value available. I have tried many china made cages, and this is superior in quality. Fit For someone new to chastity and of average size, the Amicus cage is an excellent starting point. Sure you can order a $20 china manufactured cage, but you get what you pay for. The gap sizes in those cages are all over the place. If you're new to chastity you can try several, and never understand why you are not getting a good fit or having issues with discomfort and chaffing. In the end I had another base ring made 1/16" larger and with a larger gap. It made all the difference in the world. It's quite amazing what a few millimeters will do to the fit and feel of a device. If the gap size is wrong you will have issues. Conclusion If you're serious about chastity and looking to wear 24/7 the semi custom Amicus offers a great value at less than $200 with the security screw. With the proper fit this device can be worn comfortable 24/7 for years to come. Thanks again to Mark at malechastitynow.com for the excellent service. Happy customer.
