Heres a few pictures Bassworm of the ones I have. The pictures arnt great bc I took them with my iphone, but at least you can get an idea and see what they look like on a carto and a carto tank.
A bunch of vendors sell them. I got mine from Hoosier ecig supply bc they have them for only $1.99. Madvapes sells them for $2.99 but they do have them in a few extra colors that most vendors dont carry (silver and brown ones). Crystal Clear Vaping sells them for $3.00, and while they are the most expensive of the 3, they do have free shipping. So if your going to place an order for just a drip tip or two, Id prob get them from CCV bc it will actually end up being cheaper with the free shipping. I got mine from Hoosier just bc I was already ordering some other stuff so I added a few in.
If you go on Hoosier website, the ones I have in the first picture from left to right are: O5, O3, O2, and O6.
Its hard to tell on the website and still alittle in my pictures, but the Purple one has Blue swirls, the Red one has orange swirls, the off-whiteish one has yellow swirls, and the Blue one has white swirls. I like the Blue and Yellow ones the most.
The second picture is the Blue one on a Ressurector carto on my E-Power and the third picture is the yellow one on a 3.5ml Smoktech tank with a Ressurector in it on my E-Power.
Like I said before, these drip tips are awesome and are the only ones I use now. After I bought my first Blue one, and really liked it and I ordered 3 more on my next carto-tank/extra E-Power batteries order, and they are the only drip tips I want to use now. They look nice and have a nice shape to them that is comfortable on your lips. And for $2-3 their def worth it.
Like I said, they are kinda tough to get on the first time, but as you can see from my pictures, they do fit. Follow what I said in the previous comment about putting a little juice on the o-ring when you put them on the first time and they will go on, you just need to keep turning it as your pushing. Once you get one on, Id leave it on for at least a day, and the O-ring will shrink some. Then afer that they go on and off much easier. Its still a tight fit, but not even close to as hard as it is to get it on the first time. And personally Im glad they fit like that bc they dont move at all, even with your PV in your pocket.
I also def recommend using them on carto tanks. As you can see in the 2nd and 3rd picture, the drip tips havea slightly wider diameter then the carto does. On a carto tank its good bc they stop the tank from being able to slide up, and the tight fit doesnt pop them off if the tank does try to slide up some.
I use the Ressurectors with the metal base on them in my Smoktech tank and a Big-Belly Drip tip on top so I dont have to worry about the tank sliding and leaking bc the metal base stops the tank from being able to slide down, and the Big-Belly Drip Tip stops the tank from being able to slide up.
I would def get some and I think youd really like them. Hope the pictures helped some
