Made from a super-soft OEKO-TEX certified cotton blend, the Biirdâ„¢ Holiday Socks appear to be covered in snowflakes. Look closer, however, and you'll see they are really covered in anatomically correct depictions of the clitoris as well as various sex toys! These Biirdâ„¢ socks are perfect for lounging around the house or to keep your feet warm and comfy during (self-)sex. Also a great conversation starter!
