Approximately 500 OPP bags. Since I haven't counted them all, the quantity is approximately 500. The size is approximately 15cm x 10cm in total length. The flap is about 3cm, so the effective inner size is approximately 12cm x 10cm. 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.
