I got some in Michaels, in a bag hanging on the peg wall near the small acrylic paints. I've seen similar at Joann's, but they were near the x-acto knives, not near the paints. Seemed like a strange location to me. I don't often use that tip now. I found a small bottle with a long narrow tip that has a snap on cover. Got to be careful not to squeeze too much, as the tip is a little bigger, but it is easier for me. I didn't like cleaning the small metal tip.
