When I originally reviewed the MY SIZE 47, and said I wished they had a smaller version, Lucky Bloke responded saying that the 45mm ones were now available. So of course I had to order a couple right away and test one out, when they arrived yesterday. Being near 4" and thin (ok ok, 3.75" long on a really good day, otherwise typically 3"-3.5"), this version was even better. Less loose than the 47mm, and still slightly less unrolled at the base when compared to other snug fit condoms. Really wish they'd make shorter versions, not everyone needs to unroll over 6" in length. In case you've never used MY SIZE before, they are dryer than other condoms, so don't forget to buy lube.
