Super smooth, comfortably stretchy and designed to perform just as hard as you play, Fantasia's shimmery Double Stack Rings offer up tons of playtime enhancement potential. Stack 'em or wear solo—the results won't let you down!

Combined or separate, each ring's snug pressure traps blood in the penis for a harder, longer lasting erection; you can also wear one or both over a favorite toy or strap-on for extra thickness. 

The TPE (elastomer) Double Stack Rings are body-safe, easy to clean (use soapy water or a favorite toy care fluid/foam) and compatible with any water-based lube you love.
