Okay when I first bought this, I didn't realize the second knot would be so thick... (My bad, I'm awful with measurements) It's going to take me awhile before I can reach the hilt/base. The sensation of the veins and the waves feel incredible! The insertable length is just right, like I said.. once i get to the base. The colors are beautiful.I would recommend this 100%. 5/5 stars!
