Approximately 500 OPP bags. Since I haven't counted them all, the quantity is approximately 500. The size is approximately 13cm in length x 8cm in width. The flap is approximately 2.5cm, so the effective inner size is approximately 10.5cm x 8cm. There may be manufacturing imperfections or creases. Please understand this beforehand. As these are OPP bags, the product will be shipped in simple packaging (without air cushioning). Thank you.
