Hmmmmmm........seems that we all have this issue......I wonder about somehow warming them up....would the liquid flow better and not gunk up as much?? Of course it would have to be with a heating pad or embossing gun as I sure wouldn't want to experiment and put one in the microwave!!! Although my kids might!!! LOL
You know what is funny? It almost seems like a good one is a good one to the last drop, but if the pen struggles, it will struggle all the way through. Right now I have a struggler, and it skips repeatedly. Will keep an eye out here for solutions.
