Please understand that I may not be able to reply or ship immediately on weekdays due to work. This is an item that I previously sold in my shop. It is unused. The size is 35mm for the part that receives and 20mm for the part that hooks. The material is iron. The color is silver. It is unopened, so the condition is good. It will be sold in bags of 100 sets. Suitable for trousers, skirts, etc. It is convenient because it has three stages, allowing for size adjustment. Please note that we do not sell individual pieces. (We have plenty in stock, so we welcome purchases of 2 or more boxes. We will discount the price depending on the quantity.) Please also note that the color may differ from the image. Color: Silver系 Parts: Handicrafts, handcrafts Material: Other Parts: Other Type: Metal fittings/connecting parts
