Hi konio38, and thank you for your kind words.
Yes, you can't imagine how many short sleep nights I have to spend handling this website and project.
QR Codes are now included in all boxes for legitimate reasons.
First, QR Code is mainly used to promote the website. Imagine you come to visit one of your friends and he's showing to you new cool boxes he just made for his own collection. You look at the back and then you notice the QR Code. In less time needed to think, you take your smartphone to immediately keep track on the website.
As you mentionned, QR Code is best seen on small pictures (when buying on eBay for instance). Old generic code was confusing some times.
And then, QR Codes are at the exact same position than the old generic one.
I provide the images as is, you are free to easily modify them before printing your boxes.
But if you respect my work and the free use of this website, I would expect you not doing so
