So, hello, I am going to show you how to fill up a copy sketch marker with a refill. One thing that you have to do is have a couple sheets of paper under your marker when you're refilling it because sometimes when I refill them, not always, but sometimes I will put too much ink in it and it will start coming out to the other end. So, that's no good if you get it on anything. So, have a piece of paper or like some sort of thing to keep under your marker. And then you take off both your lips on your marker and you take off the chisel tip and then after that you open your refill bottle. This is brand new, I just got it. And then what you do is you put this end into where the chisel tip was and then you can kind of squeeze it a little bit and you have to watch the bottom thing because once it turns a dark color, like once it turns into the color that you want, that means it's full. So, you just have to watch it because if you put too much in it, again it will spill all over the place. And after a couple seconds it is done. You can get refills and the markers on my online store shop.pagidraw.com. And if you do get to buy these markers, it is a good idea to get refills because you can fill up to I think four or five markers and it's like cheaper if you do it that way. So, thank you.
