I place the cap onto the bottle without threading it and push the cap at a 90 degree angle.

Use a screwdriver or a blade to pry the cap going around the rim.

Or google "shortfill cap removal tool"

I take a blade and stick it in the seam where the bottle meets the tip/cap, whatever you want to call it. I then give the blade a little wiggle in an up/down motion (when the bottle is upright). The blade acts as sort of a wedge. The tops come right off with ease. It takes like 2 seconds.

This all you need its tricky at first but do it once you got it https://youtu.be/2d9MdB2nN_M

The key is to buy better bottles and then you can freely destroy the unicorns if you need to transfer something out of them.

I just use one of my mini flatheads I got from my various RDAs, stick the flathead in and just pop it off

Use the pliers on the threads for the cap, just below the edge of the bottle maybe 3mm. Hold your other hand over the top so it doesn't shoot away and make a mess. Doesn't take much pressure so it won't damage your bottle. Use clean pliers.

I use a steak knife. It sounds stupid but I push it into the joint between the bottle neck and the tip then pull it up.

I found this works best as pliers pinch the tip of the bottle.

I use a small micro slot screwdriver that I have in my coil kit and it pops off quite easily. Just push under the lip.

It always goes flying though.

I always use the side of my pair of tweezers. Use the long side and rest it under the lip of the top. Push down on one side and it pops right off.

Reading through the comments, I guess I'm the only animal who uses their teeth hahah. Just sink them between the top of the bottle and tip and give a good tank with your hand. Obligatory ( ͡° ͜ʖ ͡°)

They do make “short fill “ bottle openers

Personally I just have a thin butter knife I use on the unicorn style chubby gorillas. (Both v2 and v3 60mls). I'm sure someone here has a better way though. Just take the thinnest part of the knife and wedge it into where the bottles neck seals with the top piece. You will see the seam of where they meet. Pry it up a little so you can get the fatter more stable part of the knife under the seam. Work it around the neck till it pops. Little harder to find with v2 but you can still see it. Will still take a little hand strength but using some leveraging and finesse hopefully not too rough:)

You can use the cap that unscrews in the same way you’d use a screwdriver to lever it off. Just jam the edge under the lip of the dropper, get it to lift a bit and then just turn the bottle and it’ll come up

pair of pliers works
