The Boundless FTM Stroker, 2 inch size is a soft, stretchy masturbation sleeve designed for trans guys and nonbinary folks to engage in stroking fun.  It is smaller in overall size than the similar Packer Gear Stroker, so it may work better for those with less genital growth or no genital growth.

Many trans men and gender non-binary people who are on testosterone therapy experience significant genital growth of the clitoris/phallus/dick (choose-your-favorite-genital-term here). Many who have experienced this kind of growth seek out a masturbation sleeve that will allow for enhanced stroking action. This sleeve is very stretchy, so it can accommodate a range of sizes.

The ridging on the inside of the sleeve brings additional stimulation.  Users will need to experiment with water-based lubrication, pressure, and placement to achieve a suction sensation during use. 

Made of a phthalate-free soft, liquid silicone material.  Wash with warm soapy water.  Use only with water-based lubricant.

The Boundless FTM Stroker measures about 2 inches tall, and is 1.5 inches in diameter at its widest point. The opening for insertion is about an 0.625 inches wide when unstretched (though the opening is 5-leaf clover shaped, not round).
