This word is from Cebuano (Visayan), a Philippine language distinct from Tagalog.
Sartin refers to an enamel-plated metal plate or drinking cup. Tagalog speakers may simply call it a tasa (generic cup for coffee or tea), while Americans may call it a coffee mug.
A sartin holds more volume than a tasa.
Most sartin cups have a blue-colored rim, and their sides are thinner than that of widely used Western coffee mugs.
Sartin is also a surname in the Philippines.
