I came across these ideas on Pinterest. I am going to use these for my camping needs. I always have extra batteries with me, we get them in large quantities at Costco. I have just rubber banded, or taped them together...this idea is great...the solution is better storage. I am officially looking for small clear plastic containers. I am also going to look for other things to put into these containers. I think small travel size containers from Walmart might work very well.
