I just received my 3.5ml tank, very scary (for me). I'll have to re-watch Snowdragon's video on how to fill them before I have a try for myself
But I love the black silicon drip tip that came with the tank. I am not a DT user really, though I have 2 Delrin DTs. I notice the silicon DTs are for sale in the very US patriotic red, white & blue. Will other colours, like BLACK, be added to this range?
