Super Glue single use minis are great for small projects. The 0.5 g tubes stay fresh making them the perfect tool for hobbyists, craftsmen and women, and specialists who depend on Super Glue's quick-setting, super strong bond for their projects, yet only need a small amount at a time. The nozzle tips easily screw on to the tube enabling precision application into tight, hard to reach locations. Best used with non-porous application parts such as metal and rubber.
