Although a long time has passed, there appears to be no rust. Some pins have been taken out of the case, and some cases haven't been opened. The case says "(Étoile)". There seem to be different types of pins, and those with labels are: ◆ 1 case of (Yanagi Pins) ◆ 1 case of (Small Pins) ◆ 2 cases of (Pin Curl Pins) ◆ 4 cases without labels ♦ The number of pins varies, with approximately 40-50 pins per case, but I haven't counted them exactly. I estimate there are close to 200-300 pins in total. (One case contains only 13 pins) ◆ There are types with a ball at the end of the pin, types without a ball, and wavy pins, etc., in each case. ◆ The length of the pins is 5cm for those with a ball / 4.3cm for those without a ball ◆ They are black, but they also appear to have a bluish tint. I think I kept buying them because I forgot I already had some at home. They are unused and in good condition, but some may show signs of aging. (I have checked them visually) 〜〜〜〜〜〜〜〜〜〜〜〜 ◆ Anonymous shipping ◆ No smoking / No pets ◆ Immediate purchase is OK, or purchase after commenting is also OK. ◆ Shipping will be within 2-3 days, but sometimes it's 1-2 days depending on the situation.
