Coffee cup is categorized into regular size and large size in café, however, the stir stick is in same length. Traditional stirrers are appropriate for large-size coffee cups, but they are too much for regular-size ones. Although the cost of an individual stirrer is low, the demand of it is enormous. As a result of that, Joint-stirrer aims at seeking a new design method of a stir stick to save more material particularly for that of regular-size cups.If your coffee is a large-size, you pick up 2 stirrers (one longer, the one shorter) and joint them together. But if you order a regular-size, you just need the shorter one.
