Knucklehead Drip Tip- 510/901/KR808d-1, Delrin

After using swivel tips for even a little while, I find regular tips uncomfortable and awkward. These fit perfectly on my Nautilus Mini. The knuckles are tight enough to stand up on their own but loose enough to move around and conform to your positioning with no effort. Plus, the delrin just feels good and doesn't hurt your teeth if you accidentally tap them. Great tips, great price.

These have a good feel and range of motion. The price is right and the service is always good. I bought black and white both.

I like this drip tip as it looks cool and it makes vaping very comfortable but it leaks horribly right at the knuckle joint really badly. So if you get it just expect this but it is really cool so I'm pretty much 50/50 on this one
