The JFGlass Custom Diffy Pump Drop 2
Ten new one-of-one diffusion pumps hand-blown by JFGlass in Southern Oregon, five for the Dr. Dabber Switch² and five for the Switch GO, the first GO customs he has made. The clear pumps restock at the same time. When a piece sells, it is gone.
The Best Pump Maker, Now on Both Devices
JFGlass built his name in the community on diffusion pumps that perform, and in our view he is the best person making them right now. Drop 1 put ten of his Switch² customs on the site and every one of them sold. This is Drop 2, and it is bigger in one specific way: five of the ten are built for the Dr. Dabber Switch GO, which nobody has made a custom pump for until now.
Every piece here is a single hand-blown original. Function is identical across all of them and matches the clear pump exactly, so you are choosing purely on looks. Pick the one that speaks to you, because once it sells there is not another.
These pumps fit the Dr. Dabber Switch² and the Switch GO, and they are at their best paired with the right cap and pearls. Tune the draw with our Switch² carb cap upgrades, and add a set of terp pearls to spread your concentrate and pull more flavor out of every dab.
First come, first served. No auction, no reserving a piece. When the clock hits zero, all ten customs and both clear pumps go in stock at once.

Every Piece, In Order, By Number
One run through all ten customs, numbered as they come up, so you can match what you see here against the cards below before you commit to one.
Worth a minute of your time even if you already know which one you want. These pieces are fumed and dichroic, and that kind of color work does not photograph honestly. It shifts as the piece turns, warm from one angle and cool from the next, and a still only ever catches one of those. The video is the closest you get to holding it.
