When it comes to strokers and masturbator there's one company that dominates the market whose name rhymes with "Fresh White". We are not associated with this company in any way, and we won't even explicitly include the name here.
Their products, along with those of most other stroker manufacturers, are typically made of TPE. This material is perfectly body safe when new, but because it is porous it must be very carefully stored. Even with proper care, after enough time has passed TPE will likely become irreversibly infested with mold or bacteria.

The Big-O Sleeve is a toy that fits in the same sized case (the full sized version), but is made of durable, easily-maintained silicone.
Past the opening, the texture of the sleeve consists of 5mm bumps. More textures will be available in the future.
All our toys are available in multiple, clearly-labeled sizes, and in two levels of firmness. Shore 00-10 silicone is the softest silicone available, but may be very slightly tacky to the touch. Shore 00-20 silicone is slightly firmer, but still very soft and not at all tacky.
Two different internal diameters are available. The size is measured as the maximum internal diameter. Bumps extend 5mm into the opening, so minimum diameter will be 10mm less than the maximum diameter, as there are bumps on each side of the opening.
The opening of the Big-O is fixed at 32mm which flows into your desired diameter shortly past the entrance.Â
Available sizes are: 28mm (tight) and 32mm (medium),
Personal lubricant is required to achieve the desired sensations. Use a water-based (not silicone based) lube to preserve the finish of the toy.
We also offer a sleeve + case combination (see separate listing for the Big-O Sleeve + Case) but this listing is for the sleeve ONLY. You will need a full-sized case from That Other Company (one that is approximately 10 inches/25.4cm long and 3.6 inches / 90cm in diameter) in order to make use of this toy.
All of our products ship discreetly, in a plain cardboard box, with a return address of "Open-Casting Tech."
