What disp vape cartridge and where to get?

Just ordered a bulk pack of disposable cartridges. Made a sample, got medicated a bunch last night. Woke up this morning and the contents of the cartridge leaked all over my battery and desk. Either I'm a moron, which is most likely the case, or these are fucking junk. Can anyone point me in the right direction for a decent 1ml cartridge sold in bulk orders of 60 or more at a time? Thanks.

junk lol.............hit and miss is my experience.

i've ordered some high quality cartridges here @ good prices: http://goldenpharms.com/product/natural/
I think this is a pretty new site, but its a great product. had no issues with leakage.
you can choose your potency i'm sure you can probably contact sellers & they'll hook you up with bulk pricing
