Crazy glue is incredibly useful - how did we ever get by without the internet? There are many obvious ways to connect things, but after reading that medics in Vietnam used it to stop bleeding and close wounds, I started using it when I cut my finger while cooking, etc .Dermabond instead, but it helped me a lot). I tried buying it in large tubes for years before realizing that I almost never use it more than once because the tube clogs after the first use, so I switched to these disposable tubes which are perfect . Thank you PharmaPacks for the fast shipping.
