TPR is a relatively good substance for a masturbation sleeve - it's phthalates free and hypo-allergenic and fairly easy to look after. It doesn't have any great scent and when you lube it up with water-based lube, feels beauty soft and 'giving.' The sensation itself is one of the major appeals - it doesn't feel as firm as silicone or rubber.
The bane of most modern masturbation sleeves is their depth - the majority are just four or five inches deep and that simply isn't enough for most men. The advantage of the Beauty Sleeve is that it doesn't have an 'end' - it's not a tube, like most sleeves, but more like a 'sock.' That, combined with the stretchy TPE material, means it stretches to accommodate even the more endowed members of the community.
The Beauty Sleeve is pretty simple - a TPE sleeve with a smooth exterior. However, enough sophistication has gone into the design to mean it does what it's supposed to do astonishingly well in comparison to other masturbation sleeves. It handsomely accommodates even larger men, and is easy to manipulate even after you pour water-based lube all over it. This might not sound like much, but given the performance of similarly priced sleeves - is definitely worth a mention.
TPE is a fairly easy substance to look after. Keep it dry, keep it away from oil or silicone lubes. It's not suitable to share with others, as the TPE is porous, but given that this is a masturbation sleeve that's probably not a huge issue.
The Beauty Sleeve comes in a beautiful box emblazoned with the picture of a Manga chick in a wet t-shirt. It's lovely, but also discrete. The entire package is about the size of a packet of toothpaste - although the day your toothpaste starts being sold with hot cartoon chicks on the box, you might want to switch brands.
Oh, boy. When it comes to masturbation sleeves, I've tried them all. For a sleeve this price, and at this level of sophistication, I was highly impressed.
I tend to be a little larger than average, and have found that a lot of sleeves simply don't accommodate me (especially the Japanese ones, sticking to a particular stereotype.) This one pleasantly surprised me by being a good size even for me.
