Sleeve kings have one of the best quality sleeves out there in the market, we were actually shocked with the superior quality of sleeve king sleeves when compared to other top brands such as Ultra pro, etc. These sleeves fit all the pokemon cards and any cards (63.5 x 88 mm size) perfectly and the sleeves themselves are much thicker in size so better protection for your cards.
