I got some great little containers for these types of things at a Japanese housewares store called Muji.
I don't think the brand is that big in the US but I see they do have stores in New York and California and an online store as well. Don't know about Canada though.
Tip: the really suitable containers are actually in the Health and Beauty section, as opposed to the Storage section. But they're really well made - soft flexible plastic, not brittle - and the right size for small items. http://www.muji.us/store/health-and-beauty/containers.html
$1.25 to $2.75 for the small boxes.
The place is like the Japanese Ikea!
