At Walmart, in the craft section, I found a package of screw on tip tops. The package is called "Fine Tip Tops" made by Plaid. They are made for the craft acrylic paint bottles and there are 3 different opening sizes. And they fit the Elmer's bottles too. .The price was either 4.95 or 5.95 for a package of 6. Just thought I'd pass it along
