I've never broken one open but I'm sure they're clear with white powder on the inside. I know mine are legit, but they are a couple of years old. Dk was some of the better mexi stuff in its day.
Mine also came in a baggie, but I knew and trusted the guy that got them for me. He would put them in baggies and tape them to his thigh when he came across the border. Easier to smuggle in a baggie than a bottle.
