Engraved with a conversion chart for the weights of gold and diamonds. This is our own brand, we have them made for us in China, it is by far the best 10X large lens (apart from the Zeiss), despite its relatively low price.
I've marked the quality as "very good" as opposed to "exceptional" because it's not quite as good as Zeiss!
