Similar story here. I got my first humi as well this past Christmas. My wife bought it for me. She went on line, and picked it out all on her own (which I think is WAY cool!). It’s a 100ct.
Up until then I was just using a basic Tupperware container same as you. I’m a noob so I don’t require a lot of storage (I know, I know, not yet anyway.) I don’t buy in bulk because I don’t have my preferences nailed down yet. Everything comes from the B&M and I only buy 2 or 3 at a time.
Anyway, Christmas day I started seasoning her up and about a week later I was transferring the few sticks I have over and my wife comes into the room and drops a package on my lap….it was a 25 bundle she picked up from the site she bought the humi at. Again, way cool, but I was like WTF, between the new, the old, and a cup of beads the damn thing is full.
That's a nice looking one you got picked out. I think for us noobs a 100ct is a good place to start, as long as you’re not planning to buy in bulk. Or at least have additional storage plans for that bulk. I like you plan to fall back on the Tupperware.
