Hey, I bought a GIANT bag of these 3/4 inch videotape containers. They look great for geocache containers, the only thing you have to do is use ziploc baggies for the contents. They are black and made by 3M. If you want any of them, I'm selling them for $1.00 a piece. I'll bring them to the Spring Picnic also. I'll ship them to you for $3.95 if you need them now, otherwise I'll get it to you @ the picnic. Thanks! ~Chris
