The maker(s) must've been listening to Rihanna, these cards really know how to shine like a diamond. Ofcourse in (direct) sunlight they shine the best, but even in the dark they are beautiful and still shine. they can chip on the edges with normal play quite fast. 4 matches with 2 persons each like 15-20 minutes. and 7 cards had chipped. We both love and collect cards and know, how to handle them and practice cardistry, so u get my point. With all of that stil nothing major and u can fix everything with just correcting them with another card!
