If you're ever in the PoCo area, we have lots of Java moss, flame moss, weeping moss and sometimes Christmas moss as well it's in the 1-2 Grow cups so they are guaranteed free from pest snails and other things. Petland PoCo
If you come by Richmond, I can trim you a lot of mixed moss - java/flame/christmas. Depending on how much comes out it will be 5$ (golfballs+) or 10$ (baseball). However... it may contains snails haha.
