Dear Seb Cox, Happy Chinese New Year. Hope you are great. Looking back it was the year 2005/2006 I got the Pantra, and have enjoyed it ever since. I recently came across your website again and read you are/were intending a new one with vibration? Is that one available already? What I have been wondering is if there is a material available that actually “swells up” inside if influenced by the warmth inside, so that it may fill the “gaps” inside a little better and the prostate pressure points more fully. Thank you and enjoy the evening, all the best. Mr H.
