Approximately 300 OPP bags. Since I haven't counted them all, it's approximately 300. The size is approximately 10cm x 20cm in total length. The tape part is about 3cm, so the effective inner size is about 10cm x 17cm. There may be manufacturing imperfections or creases. Please understand this beforehand. Since these are OPP bags, the product will be shipped in simple packaging (without air cushioning).
