Super strong vacuum with improved size. Due to the larger size, the air volume can be captured in and the vacuum is large. You can enjoy a roomy deep insertion with the super vacuum Ultra-soft design that tangles and has special details and soft gel, so you can enjoy the pleasure of tangling with it. Experience a snuggly and hug vacuum with a newly born soft-type U.S.Tenga. About the Size: This product is designed to be approximately 1.6 times the volume of the regular size cup series, but it is not a cup specifically for larger sizes. Even those who feel regular sized cups just right, this cup series can enjoy a spacious and deep insertion experience with a large capacity vacuum.
