BOTTLE NOT INCLUDED.

Colors of caps may vary depending on size chosen.

These caps are fitted with a pierceable seal that will allow you to puncture them with the needle of a syringe, but remain water-tight to prevent leaks.  This is perfect for avoiding spills and keeping oxygen from getting to your E-Liquids.  This is the perfect cap for DIY E-Liquid mixers.  With these caps you can use a syringe to remove the desired amount of liquid without ever having to remove the cap.
