Things I liked:Great BB for the Price. BIO & GREEN are a plus. Bought these for my Airsoft .30 cal Machine Gun and I am told it looks like "Green Snow" when I am shooting. Things I would have changed:Packaging like the other review said. I have a air tight Plastic bottle I transfer mine to as well. I put in a small Desiccant bag in mine to keep moisture out. What others should know:Respect the Field you play on and the Owner. Think BIO and think GREEN.
