Styrofoam

Is it safe to use stryofoam for containers? I assume not, because they are made from some nasty things, and light and water tend to break things down. But... these containers i found would be perfect! Cant toss them without checking with RIYOU!

Dude...Use em! Aint nothin wrong with styrofoam except when people throw it out their window, which could make a nice home for a bug or sumthin but still...dont litter. lol peace!

check out this journal, it's kinda long, but it's possible...
