## Frequently asked questions

#### How do I properly care for the rings after use?

Since the material is a high-quality Thermoplastic Rubber, it is important to clean your rings thoroughly after every use to maintain hygiene. Always check your rings for any signs of wear and tear, and ensure they are stored in a cool, dry place away from direct sunlight.

#### What kind of lubricant should I use for the best experience?

To keep things smooth and comfortable, we always recommend using a high-quality water-based lubricant. This reduces friction against the skin and makes the application of the rings much more enjoyable.

#### How can I best utilize this expansion kit with my existing gear?

This expansion pack is perfect for increasing customization by allowing you to stack the two additional square donuts with your original Boner Kit. These rings are designed to integrate seamlessly with your existing gear.

#### What are the dimensions of the rings?

The ball ring has an exterior dimension of 1.3 by 1.3 inches and an interior dimension of.9 by.9 inches. These dimensions are key to how they stack.
