Can anyone tell me what this bottle is?

I got 6 of these bottles from the recycling depot at the tip, and i've never seen them before. They are dark green, and 750ml in size. The only markings on them are some dots and letters along the bottom edge of the bottle (8 dots and 17MA5354-W).

Anyone seen these before?

They usually come in tens and are found on top of walls. You have six which accidentally fell. So the other four green bottles are still hanging on the wall.
