the cloud is stamped in a dark silver ink; the double-line effect was actually an accident (i think i pressed the stamp too hard) but i really like the result! you can also return to activity the same day. is it necessary to register my trade mark or can i sell my product without doing so? used (normal wear), in pretty much perfect condition, my baby loves it but is starting to crawl so time to get something for her size. at last the blessed generator kicks on. > >>> unfortunately this must be done by hand.
