It's a press fit valve system. Once you fill it and snap it on your going to need a knife, pliers and some strength to refill it. Also the nib is trash (stringy lines) Sorry AP I love 99% of your inventory, but you shouldn't of put your name on this marker.
Great marker overall, however, DO NOT add flowpen to this. It makes it super thick and when you write with it, the ink does not dry. So other than that, I liked it.
When you run out of ink, and you on a budget. I recommend buying Milwaukee permanent markers in a 3 pack and take the ink out of that and use some sort of tool (think creatively you artist you) and squeeze it into a funnel that you have stuck in your 367 marker and there ya go. Same coppery finish. It may be molotow ink haha. Then watch GR video on how to recycle ink on YouTube and your good to go for long time.
