For those of you that live in humid climates, or are concerned about humidity issues as regards your hardware-DE and str8 razors, blades, and the like, I chanced upon this site today: http://www.silicagelpackets.com/. Seems like they have a good variety. Can't vouch for them, just found it today, but I will be buying some to protect my blades, as I do live in a humid place.
