One unopened bag (100 pieces) and one partially used bag (50 pieces). The leads are bent inside the bags. The products appear to be free of rust, corrosion, and dirt. There is some minor scratching between the products. The plastic bags are dirty. Shipping is planned via Yu-Packet Post or Nekopos. #Bulk purchase welcome with other items.
