Hi all, I want to share my experience with the new sleeve. I plaza ordered also ordered the handsome mouth seals. I use a 2.5 inch receiver and ordered 2.5 inch liner. I tried all three configurations. The one I like the best is sleeve over the 2.5 inch liner handsome mouth constrictor wraped by liner. I’m a little big in girth for the largest mouth seal that I can’t go to fast. The tightness of the seal and then going into the tight sleeve was really great. The mouth does fit over the 2.5 inch tube. I also use electro stim with the Venus which really feels good.
