My second CBG was given to a child and I wasn't too worried about it being "politically incorrect" on account of the smoking connection because his parents are smokers. But, I probably won't do it again. Instead, I'll use a school box like this from Amazon--This box is manufactured by General Box Company, Waycross, Georgia, USA, and they sell this and some other school boxes at http://www.amazon.com/s/ref=bl_sr_office-products?_encoding=UTF8&am... . I have one of their older boxes and it is 8 3/8 x 5 1/2 x 2 3/8 inches or about 21 x 14 x 6 cm.
The company's web site has some interesting information at http://www.generalbox.com/html/history.html where you learn that the founder invented the hinged lid box in 1938. Aside from being surprised that you could get a patent on something so simple, I was happy to learn that the company is still in business and making lots of boxes here in the USA.
