These are all drip tips made of high quality stainless steel. Their weight alone lets you know it is a quality product. They are all 510 drip tips that will fit most 510, 901 or 808 cartomizers or tanks or similarly sized items.
The Knucklehead is a swivel head that enables you to tilt the drip tip at an angle for a comfortable vaping experience. The rest are named based on the first impression we got from their look. These will all compliment any mod or APV!
