It's from Avid Vapers.
Bullet Cartomizer Punch - Avid Vaper

The one we use at work is amazing. It stops where it needs to stop, and it makes a huge freaking hole without warping the tube.
I couldn't find the one we use at work online, so I ended up getting a different one from Amazon (Supco BPV31 Bullet Piercing Valve - Amazon.com) and the holes it punched were tiny. I need a bigger hole for my Boba's. So I ordered the one I pictured above.
Anyone use this specific tool and knows if it makes a BIG hole? Or a little hole? I know big is relative, but the first one I bought off Amazon won't cut it.
