The bottle is heavy glass, and tinted from light to dark amber colour. The product itself isn't sticky, and seem to make my skin a bit softer when I use it, but apart from that has no real effects. I love using this product purely because of the packaging though. The metal cap is actually a twist-up button that you use to fill the dropper up with product. If you are looking for a propolis product, this product is 50% propolis, so a good place to start.
