ECO-P / Poker


Since invention, playing cards have always maintained its classic rectangular shape. But its rectangle makes it not easy to clench. During some card games, a player may not hold all the cards due to restrictions of his palm’s size and his palm may feel pain due to long-time playing (especially the root of thumb).
 ECO-P, by reshaping its figure, makes it take up less space and be more comfortable to clench, helping the players hold more cards and relieve their palms’ fatigue.
It is worth mentioning that ECO-P’s shape makes it possible to use less material in the production process and it is environment-friendly.
