When I first purchased my Gocco supplies, I bought a pack of ink cones. I originally thought I'd use these to store my leftover inks. Then I came across little containers at Michael's and decided to store the ink in there. To use the inks, I just scrap it out with a spatula. It's messier and harder to get the spatula into small spots with finer detail. That's were the ink cones come in handy.
First I fold back the top and turn the ink cone inside out until I reach near the tip (were I'd like to start filling the cone).
Once I've filled it with ink, I twist the top and seal it with tape. Snip the tip and you are ready to ink.
Much more precise, less wasteful and definitely less mess. I liked applying with the cones. I'll make sure to stock up on these before their gone.
