I have a few Indian spice in individual bottles but what if I do this:
put each of them in ziplock bag and then place all these ziplock bags
in a big airtight rubbermaid container? I am assuming that these
containers are airtight. May be not enough for spice? Then is there
anyhtign made of plastic, i.e light material to store them and in fact
minimize space by placing them in the same container. I use them
rarely but I want to keep them; I am not ready to leave them behind
when I move.

I also have raw sesame seeds in a bottle. I was going to make hummus
but never got aorund to it except roast some of them. Bottles are
heavy to carry when I move. Even if I hire people, I still have to put
them in place. Beside, there is space issue in th condo I will be
moving to. So what if I put them in seperate ziplock bag? Do I need to
place the bag in airtight container? I have lots of rubber maid
container.
