BOSS Silicone Stopper Butt Plug 9
This is a BOSS series butt plug number 9 by MODE-design. Like other versions (No. 1 - 8), it uses high quality silicone and its surface finish is silky smooth. One major difference is MODE-design uses hollow design, meaning inside of the body is emptied out in order to reduce the weight. As a result, it has some give but it's not that noticeable. Also, since inside is removed, there is no ring strap on the bottom like you see on other BOSS series 1 through 8.
