When you order from Perth mint. The tracer will tell you . Today we have received your order. Then today we are picking your order. Then today we are shipping your order ect ect. Then bars arrive ...Always makes me wonder . WTf...... What they are picking them from ...LOL
I just went and had a look at a few I have from about 4 years ago. Whilst they've tarnished slightly (easily cleaned), none of them have these "birthmarks". Interesting.
