Great for stretching silk and other fabrics for painting, and they don't stain the fabric when wet because the pin part is stainless steel. The handles are sturdy but light weight aluminum. They actually have many more uses than stretching fabric. Way stronger than the plastic ones you get at the store. My "useful stuff" (junk) drawer would be naked without 'em!
If you notice a grayish residue on the heads of the pins it is from the zinc stearate that they used to lubricate the aluminum heads as they go through the machines. The zinc stearate is not harmful (it is actually a common ingredient used in foundation makeup). To remove it, either some dish soap and hot water, or alcohol should clean it off.
100 pins per box.
