Tiger "Insta-Cure+" glue is a powerful cyanoacrylate-based adhesive and bonds permenently in 5-15 seconds. This quick-drying glue fills gaps and is great for attaching replacement tips to ferrules. It bonds so quickly and permanently you don't need to use a tip clamp. This large bottle (one full ounce!) is enough to do hundreds of tip replacements and is handy for all sorts of general repairs.
