I think these vials are rather cheap. The ones we use are purchased in bulk and don't cost much at all. The only added value to the ones you have, are that they are exactly the correct ones (if it are those with the screw-on caps). I think half a dollar for one vial is the max fair price, in my opinion (the ones we use are just a few cents a piece, if you devide the bulk-price by the amount of vials in one package).I have a good portion of vials that I picked up a while back. I was planning to distribute them but never really got around to it. What would be a fair price for a set of 10 without labels/coloring?
