Bests & Worsts Reviews from Amazon

I like the idea behind it, and they worked fine I suppose, but I wouldnt recommend this product because they arent refillable. I might try to find a way to get past that and hack into the paint reservoir, somehow...but I shouldnt have to do that. Its a typical ploy to get you to repurchase their product, so they make them one time use pens. ** Ok i was easily able to refill the pen. I overreacted lol Its not hard, its just got no instructions to help you do it. I popped off the end cap (careful not to break off the other plastic piece thats visible inside the endcap). Then twist that white piece on the end now, the opposite way than what moved the seal up, until its back down. Now that theres room for more paint, replace end cap. Pop brush tip off, refill pen just as you did initially.
