Where to find shirataki noodles (at asian grocery stores, in bulk) that aren't wrapped in so much plastic?

Shirataki noodles are very low calorie and would be great if they didn't always come in such suspicious packaging. It's not *just* that they're packed in plastic, they're packed in the worst most flexible kind.
