50 bottles of very strong flexible plastic quality. in two small zip bags aside 50 caps and 50 caps Dropper. Really perfect for e-liquid is the same. The dropper allows both accuracy and also a quick filling. I find these far more practical and durable than those bottles which are sold in the e-liquid trade. Another point importantly, zero leakage and a thread that collects the successive openings and closings. Those receipts are semi transparent to what my use is no problem. I will take in because this is probably the best item at the best price I could find for this use by far.
