Love this #49 tip on my Tesla Punk Mini PV, with a Crius 2 RTA tank, and the glass/brass color matches well.... very Victorian era laboratory look. Its a bit too wide-bore for my ideal, but totally vapable. All in all, great deal, and cant wait to grab the copper one to match my guy's Tesla Punk.... those PVs are not easy to find tips to match, so these were a find! Base Hole may be a bit smaller than some of my other tips, but I've noticed no affect on my vape. Vapes great, looks outstanding.... all in all, I'm thrilled. Yay, Eciggity! More tips in Vintage Brass and Copper, please!
