These dildos are ready to be paired with a harness and worn during strap-on play! Dildos are penetrative toys, and these all have a wide base that will insert into most harnesses. In addition, these toys are safe for both vaginal and anal penetration. To make sure that the dildo you choose will fit your harness, check the diameter of the toy against the diameter of the harness's ring. Or, look for a harness with an exchangeable ring for extra versatility!
