What does Blue Dot on a box means?

[RMC33]

Nothing. Nothing at all. Does the lens function, look/feel new and take pictures? If yes then you have little to no concern. As others have said, stickers are used for inventory purposes. Canon does not use stickers for inventory in their warehouses, it's all RFID tags somewhere in the box (more likely NFC). Go out and take some pictures and enjoy your new lens and let the worry go~

What? the mystery of the blue dot is still not solved? highly irregular ;D

the blue dot is special lens that had finger prints of Canon CEO inside one of the lens elements.
the yellow dot is ... Nikon CEO.

Hope it helps

I guess it is an indication that you have won the prize award for the 2013 Canon annual luck draw. I heard that the prize is a C500EF/PL with a full set of the cinema lenses.

Congratulations.

Probably inventory control. Have you checked age by serial no/date code?

I would send it back if the sticker was on the front element.
