Where do I find clear plastic Christmas balls to decorate and hang on the tree?

I'm strictly looking for the plastic ones that are split in half. Most stores carry the glass ones but they break very fast. I've acquired some from a while back but they very rare to find nowadays. I think glass sell because they are easier to break and need to be replaced more often.Where do I find clear plastic Christmas balls to decorate and hang on the tree?
I found them both at Michael's craft stores (in 3 different sizes) and at WalMart in 2 different sizes. The ones at WalMart come in packages of 6 per pack and the ones at Michael's are 4 per pack.Where do I find clear plastic Christmas balls to decorate and hang on the tree?
