This Tip Kit is from Bearly Art Precision Craft Glue. This kit contains all the replacements for your original Tip Kit. Each tip is designed with a special base that securely locks the tip into the cap. This includes an ultra-fine tip, a fine tip, a storage tip, and a cleaning pin. The Ultra Fine Tip is made with a stainless steel end and a plastic base. This is the most precise tip. The Fine Tip is an all plastic tip that is designed for crafts that require more glue but still need precision. The Tip Cap is a quick and easy way to keep your glue from drying out. The cleaning pin will help unclog your tip if it gets clogged. These replacement tips fit the 2 ounce and 4 ounce bottles. They do not fit The Refill Bear.
