Query: Plastic Mandrels

2 Ring Sizer Stick Beautiful Black Plastic Mandrels RS5You can't beat the price for 2 mandrels. They are plastic & actually larger than I expected them to be. I have not owned a mandrel before, so maybe they are all this size. I have rings that I trade/sell online & just wanted something to use for taking pictures of the rings showing the size. It works great for that. I have no plan of using them for making jewelry, so have no opinion on that aspect.
