They do come in/out of stock periodically, and pull the part number when they have run out in the past.
I'll be honest, after using these vs the boxbox pencil containers ($3.99), I prefer the Boxbox ones. I find these pencil boxes are a PITA to open without disturbing the ants, and if you add any sort of medium like hydrostone to the bottom, you have to notch out the area so it doesn't get any medium or it's impossible to open. They also aren't easily stackable. That being said, they do have the nice small size going for them and cheap when in stock.
This is the container I am referring to:
