Hey Mcol,
First, Hazelnut is DELICIOUS! Especially with some Vanilla Butternut.....
Second, I found that a bit of squeezing, pushing on a side, and pulling up while spinning that dang cap gets it off. Doing the same in reverse also has not led to leakage (in my briefcase), either... to the point that even though I have spare caps from empties, I haven't bothered to replace the broken ones..... Of course, I'm so far behind in the thread, that you probably already know this, but if I don't respond now, I'll NEVER find your post again to quote for context...
Third, are you the one I blame for Pink Champagne??? I thought it was kinda "meh" when I started vaping it at 4 weeks, and now, I think I need a big bottle of the stuff! Yep, I think it was you.....
Happy Saturday to you and all the MBV Denizens!
