I've bought this glue a bunch of times because I like the brush applicator, but it's basically a single use item. Once you open the bottle, no matter how quickly you put the brush back, you have a few days at best before everything in the bottle dries into a block. Last time I bought 3 different bottles and two of those dried up in the bottle BEFORE I opened them. It had been more than 30 days since purchasing, so I couldn't return them. So those weren't even single use.Bottom line, this is a great glue if you're willing to spend $8 on a bottle of glue, open it as soon as it arrives, use it once, and throw it away. Personally, I think it's a rip off.
