Milk Bottle Tops (Tillydrone AB24)

Thanks for looking at the post.
I am saving Milk Bottle Tops of any colours i.e. pasteurise (blue tops), semi-skimmed (green tops), and any other colour tops. The Milk Bottle Tops are going towards a charity for Blind Dogs.
If you have any spare at all that you can save would be a great help.
I can come and collect as long as it is in Aberdeen area.
Hope anyone can help.
