This BURSA card holder is a pretty slick everyday staple, made from proper cow leather with a polyester lining. It feels really nice and solid in your hand, but it's super slim, so you can just chuck it into a pocket or even one of those tiny bags without any faff. ADERERROR have added their signature touch with a subtle blue logo on the front, which just pops against the classic black. And seriously, the contrasting blue stitching around the edges? Such a cool detail, gives it a modern edge rather than just being another plain card holder. It’s a decent size too, 8.5cm high and 10.5cm wide, so you can definitely fit your cards and maybe a few folded notes without it feeling bulky. Basically, it’s all the bits you need, none of the extra weight.
