Where to buy silica gel?


Is it true that below 20% humidity consider too dry for storage?? As written on drybox instruction, it said keep in between 25% ~ 60% ..

Since you are at Jurong Point... next time, you might want to check out Challenger in IMM building. Not sure how much it cost, but I saw them there once.

Tks..
