Is the carts fill difficult？Of course not， let me tell you how to fill them

Thanks for your order of vape carts from our company, pls read this document seriously when you open the packages:

1. Pls check all packages if anything was missing or broken, if so, pls contact us immediately, then we will try our best to help you solve the problem.
2. There was an Oilfilling Manual for most kinds of vape cartridges, pls read it carefully and do as following:

1).Pls fill in along the glass.

2).Pls fill in about 90% oil ,not full, or it will be easily overflowed.

3).Screw in or Snap on the tips asap. after filling oil, or it will leak.(Snap On Carts need Press Machine, don’t do it by hands, thanks.)

4).Upside down for 25-30 minutes, or the remaining ail pressure in the tubes might be make it leaking.

Thanks and sincerely yours
