Michael's sells the tips. They were in a package with 2 tips/2 small bottles in the aisle with the acrylic paints. I think I paid $4 with a coupon and gave the extra set to a friend. But I will say, I often use it without the tip, just what's on the small bottle. If I'm careful, it's not too much. I hate cleaning the small tip and keep poking the cleaning wire thru my finger.
