Square Resin Drills For Diamond Painting or other crafts. #666, matches DMC Bright Red. For diamond painting kits that are missing colors, or to convert your own pictures. Flat back, square opaque faceted top, of about 2.5mm size. These are the prepackaged standard small size bags, allowing for 200-230 drills in each bag. For small, single orders, up to about 5 colors/bag, these will mail in a regular LETTER envelope; no tracking. More than that, they will ship in a small package envelope. Please contact me for special pricing on bulk orders, or bulk amounts of one color. I will be trying to add nearly all the colors, in both square and round, and the clear rhinestones and special shapes, if I can get those. Let me know if there are certain ones that you need, so I can get them ordered, as they do take several weeks to arrive. If you need assistance with kitting a project, or would prefer a kit completed as a commission item, I'd be happy to do a quote. *These ship to the USA only.* See sales record for shipping info.
