Instant Krazy Glue Color Change delivers the same strong bond as instant Krazy Glue but it goes on purple and dries completely clear. The Single-Use Tubes 4-pack is specially designed for single-use application. Simply, twist the self-piercing nozzle to open, use and throw away. Its convenient plastic storage case allows you to carry it in your purse, briefcase, backpack and store it at home in the kitchen, office, garage, basement anywhere you may need Krazy Glue. The Color Change Brush-On features a brush-on applicator which provides excellent surface coverage that s easy to control on large surfaces and in hard-to-reach areas. The brush stays fresh in the no-clog bottle and the bristles of the brush don t stick together.
