Looks a pretty colour inside now .
We used to peel golf balls when young as inside there used to be a stinky rubber paintball . I remember my older brother throwing one at me I was covered in it , he was " terrified" of my Mum's reaction when we got home but she just laughed and laughed . I had my new red Ladybird ( not sure if Ladybird exists now as a clothes brand) sweatshirt on too!!!
