Ordered two of these and I was able to use one for a couple of projects. One I opened, used a couple of times, then let sit with the cap on, in a cool dry place. When I tried to use it for another project, it was almost solid, but I was able to use an applicator to pull out and use what I needed. The second one I left unopened, stored into the same cool dry place. I just tried to use it to work on a broken wrist band, however, the glue solidified. What a waste.
