There is a seller on eBay that sells those, and they ship from China. The bottles have markings every 5mL, up to 50mL, and they're super easy to squeeze to dispense the eliquid. @Mowgli posted about those probably 2 or more years ago. According to him, he likes them so much that he has hundreds of them in his stash. The seller sells 6 different sizes, but I ordered the 50mL ones because those seem to be the only ones with the markings on them. They actually hold more than 50mL though (approx. 67-68mL IIRC). The markings just go up to 50mL. Here's a link to them.

I got 50 of those same ones (it seems) from Newfrog many years ago.. I probably haven't quite gone through 15 yet - although a couple, so far, were leaky. If they are the same, I have them recorded at 59 ML to lower neck cavity (but aim for 55 for best shake-ability, which naturally ends up coming out at ~58ml for me, anyways
Thanks for the link though.. Added for future reference. They are pretty nice bottles, though. Some tops don't seem to close well with some of them, but they're still good overall.
The problem is I rarely make over 10ml these days (often start with 4ml for leeway in adjusting percentages), since I have so many flavors now to play - I mean, mix with. And those are the ones I really want markings for, for adjusting percentages of test mixes.
Right now, I make do with a 'prototype' 10ml bottle that I've put markings on myself, for comparing how much may be left in a bottle before adjusting (required by juice Calc).. But the markings are rather clumsily drawn. It seems to work well enough for these purposes, but it'd be nice to find ones with etched markings for a bit more accuracy.
