● Barbashi masu yawa, juriya mai zafi, juriya na lalata, tabo ba inda za a ɓoye
● Babban elasticity, free mikewa ba tare da nakasawa, mai hana ruwa da man fetur
● Tsarin rataye, ajiyar sarari, kariya ta hannu mafi aminci
● Concave na ciki da convex, dadi kuma maras zamewa, zafin zafi da kula da hannayenku
