The size is marked in US and mm in large. The body is a hollow tube, with tip plugged in one side and cap plugged on the other. The join between tip and body is almost imperceptible to the touch, which means you won't have to work when sliding stitches over it. The tip has a short taper that steepens at the very end. The smooth plastic introduces moderate drag over stitches, holding them snugly in place.
