Steel Butt Plugs are similar to glass plugs where you can integrate them into temperature play.  The main difference is the weight difference that steel is much heavier than glass and feels more dense.  The best steel butt plugs are made from Njoy. They have different weights with corresponding sizes. The curved stems are perfect for the curvature of your body.
