I'm looking for rubber mandrels that would be good for jewelry ring repair and would order the drums but even better would be if you have some with a gradual pitch on them (I've attached a photo of what I'm really looking for for your review but again, if I can't find a pitched rubber mandrel like the photo I've attached, I'd still be interested in a flat drum like these if this is my only option.)I show you are advertising this product for .01 cents / unit and wanted to confirm the price. I want to buy atleast one of all the sizes you make to sample all first to confirm what we need to import in bulk for resell. I'll need to know what the minimum order you require for an initial trial before my primary order. Please contact me asap as I'm very interested. Thank youMichael D oceanpro1Great Product Imports, llcThey would have a gradual cone pitch to them. See attached photo for what I'm looking for. Show More
