any type of glass jar, plastic spice jar..... I re-use plastic spice jars with the shaker tops for pepper powder, works just fine. And a 'cool dark place' is just your normal spice cabinet. Nothing special, just as long as it isn't over the cook stove.....

We have powders that are probably close to 10 years old. My husband adds a couple dashes of powder to my wintertime soup for my lunch on job sites. It's kind of a game to figure out what powder it was, red blend, yellow blend, smoked paprika, chipotle, volcano dust, one of the other powders we've come across over the years. Sometimes, the shake is a little heavy.....Yowza! But I will never complain....He takes good care of me~
