Due to customer demand Castle Supply is happy to announce another addition to “THE BIG GIRL VEE” she CAN have a urinating bladder attached to her. And we’re calling her “THE BIG GIRL BLADDER VEE“. She has a vaginal opening almost twice the size of the others, larger labia and creates an amazing camel toe. The Big Girl Bladder Vee will hide your genetalia and allow a complete feminine illusion with gusto and comfort.



This Is Why We Do What We Do – emails like this…

My V string arrived Friday. I haven’t been out for awhile and decided to go have a few drinks at a T friendly bar near me, while testing out the v string. It was awesome. I love the v string. About an hour after I put it on, I noticed my posture and movement have changed. It was so wonderful to not worry about something popping out or getting loose and ruining my body language. I felt calmer and more relaxed than ever. So much so that I “forgot” about my male genitalia completely. Thank you for such a great product, I finally feel like me.
Happy Customer

One of our first customers, Robin, tells us:

“When I wear my Vee-String, the latex warms up to my body temperature and it becomes like my skin.  It is thin enough to allow the feeling to come through to my skin. I experience sensation where I rub.  I have had my Vee-String for years and it still works just like the first day I got it.  I’d say it’s durable and long lasting.  Bottom line, I get just as much erotic pleasure from the Vee-String as my partner.”
