Ordered the Sheath in size small, Soft firmness. The colors I chose were Brilliant Gold (primary) and scarlet (tip). I probably should've ordered a Medium since the Small was a lot tinier than I expected. As the first proper silicone toy I've bought (even if it isn't really a "toy") this was my only mistake! And it wasn't on Vulpini themself, just on me for not spending the extra 15$.
As a packer: I've worn it out and around the house, and it produces a bulge as expected for it's size, which is proportional to my body. I'm rather confident that the Small is so small that I don't need to wear a packing harness or anything, I can just throw it in my boxers, lol.
Very happy with this product, I'm currently looking at ordering another when I've got the monies, haha.
I love the little freebies too! The mini peen is very fun to fidget with. :)
