Our Stainless products are made of 304 Stainless Steel - this is a low nickel content stainless steel used in jewelry and surgical instruments. These weights are shaped in an anatomically enhancing shape for discrete wearing and are 1.375" around with threads on both ends of the weight. They screw into our retainers and each other with ease. This weight system is unique because it allows you to upgrade the amount of weight you use as you progress through your journey to ensure you get the right amount of weight.

16oz is often considered the magic amount of weight to get your skin into the mitosis stage which can help you make gains. But dont worry, you can always add more weight later if you need it!

Items included in this listing:

• 1 Standard P-tainer

The included Injection Molded Weight Spacer fills the gap between your retainer and the first weight to ensure a natural look and shape when wearing the device - the spacer is also used to hold the Safety Strap in place to catch the weights if the retainer slips off.

There are 2 bulges included with this set - the Injection Molded Retainer Bulge for when you wear the retainer by itself, and Injection Molded Weight Bulge to ensure a natural look under your clothes when using the weights. Using these bulge and spacer pieces ensure a natural shape while wearing the weights, making it much less obvious that you are wearing a device.
