Found these at the local Hobby Lobby. They are normally $3.99, but with the 40% off coupon they always have it ended up being around $2.50 with tax. They are plastic with foam inserts in the lids and nice wide mouths for larger jigs. The second photo shows a 1/16 round head with #4 hook.
I get mine from uline also. Work buys a lot from there so I don't have to pay for shipping. Those small ones are really nice too. I used to use similar ones like that and still have them around. I like to mix custom colors in them to see how they turn out.
