How many ml tank 510 hold?

[fairweasel2323]

I was wandering I hadnt had time to measure yet and thought maybe someone already did. Does anyone know how much e-liquid a tank for a Joye 510-T holds?

I bought a couple of packs of tanks and mine came in two sizes. The smaller ones are about .5 and the longer ones are about .7.
