Bishop Acrylic Drip Tip
This is an awesome drip tip made right here at MadVapes! It is carved out of acrylic on our CNC machines and then polished to give it a nice finish.  The curves of the pipe really bring out the detail in the acrylic. The drip tip fits 510, 901, 808 and other similarly sized cartomizers, clearomizers, etc.
They measure about 61mm (2.4″) in length and are about 19mm in diameter at their widest point.  They have a great feel when you vape.
Price is per drip tip.
