Tourmaline beads, olive and amber colors. Set of 4 beads. I'm selling these as I don't use them. *The smooth rondelle (button) beads cost 400 yen each. Please note that these are not defective goods. Please check the size in the photos. Regarding the hole size: Artistic wire 0.5mm passed through the smooth rondelle and the short columnar beads. The longer columnar beads are probably secured with artistic wire 0.4mm using a wire wrap, but I think 0.5mm will also fit. Since they have not been used, they are listed as new and unused. Please understand the above, and also understand that it is difficult to reproduce the exact colors in the photos before purchasing. I take photos to show the colors as accurately as possible and to make the size easy to understand. Please refrain from cancellations or returns due to reasons such as "it was different from the image." *I also have many other natural stone beads for sale. If you wish to purchase multiple items, please use the combined purchase function. I will discount the duplicate shipping costs.
