Those measurements show the significant difference from the small to the large. I got the small in firm just as I did the large so the other thing that changed between the 2 are the colors and the measurements.
To get information on material used and design please refer to my Original Review for the Kelvin Large
My Experience
While I chose the small knowing I could conquer it, I was let down. I could feel the texture which was great but as the Kelvin Small is only 6 inches with 5 of those being usable I wasn't getting the penetration I wanted. I am thinking I should have went with the Medium Kelvin over the small.
Thanks Bad Dragon for allowing me to try Kelvin in a different size!
