Thank you for viewing! This is Artistic Wire Gold 0.41mm 5m. The thickness is 0.41mm, and the color is gold. ⚠️ Please note that the thickness and color may vary slightly depending on the lot, especially for repeat customers. 5m is 650 yen. (This is the thickness I use for the eyeglass clasps of Czech drop beads.) If you purchase only wire, it will be shipped via mini-letter. You can purchase multiple items with different thicknesses, and the discount will be 50 yen from the second item. (In case of multiple purchases, it will be cut in 5m increments.) If you use the bulk purchase function, please select without a discount. We will change the price after the items are combined. #Chieko's Fittings Thank you!
