Every Bluelab pH pen and probe stores wet — the glass tip sits in KCl solution between uses, and a probe left dry drifts, slows down and eventually dies for good. This is Bluelab's own laboratory-grade solution, made specifically for their pH pens and probes, to keep response fast and readings accurate for the life of the instrument.
