Open away. I have 60-70 jars in rotation. Hahaha!
I have a drawer full of 4oz Ball jars with different blends:
36 Pack on Amazon Here
They hold a 2 oz tin easily. I also have some similar plastic baby food jars I use for travel.
I've given away a number of these jars when a friend said they liked whatever it was they were trying and I just gave them the whole jar.
I also wash and reuse the jars but replace the lids.
Easy peasy, lemon squeezey
Buddy, I've been pipin' for 15 yrs now, and I'm still in that phase. Same with beer. There's always another to try.Haha, I understand because I also have a lot of open tins. I transfer to mason jars as soon as I open a tin so there are no worries about it drying out.
Sometimes I obsess about finishing a tin or two before opening a new one, especially if I have, let’s say, five different VaPers open. I may want to finish one or two before I pop open a new VaPer.
In a way, I’m still in the “smoke as many blends as I can to see what I like” phase. I’m enjoying it to the fullest!
With all that being said, sometimes I just pop a tin because I want to. Simple.
