中性笔

书写介质为水性的称为水性圆珠笔（水性墨水笔），亦称为宝珠笔、滚珠笔，兼有钢笔和油性圆珠笔的特点，书写润滑流畅、线条均匀笔杆、笔套有塑料注塑成型、不锈钢材冲压磨制、不锈钢制造三种制作方式笔头分为炮弹式和针管型两种，分别采用铜合金、不锈钢或工程塑料制成球珠多采用不锈钢、硬质合金或氧化铝等材料制成，中字迹球珠直径为0.7毫米，细笔迹球珠直径为0.5毫米储水形式纤维束储水和无纤维束储水两种，常用的墨水色泽有红、蓝、黑、绿等。我们知道钢笔又被称为自来水笔,是因为钢笔水本身就是自来水和水溶性墨粉调治而成,因此钢笔是水性笔,圆珠笔笔芯内的液体是一种油性的.因此圆珠笔就是油性笔.而中性笔内的液体既不同于钢笔水又不同于圆珠笔芯内的油性液体，而是一种有机溶剂,所以被称为中性笔中性笔内装一种有机溶剂，其黏稠度比油性笔墨低、比水性笔墨稠，当书写时，墨水经过笔尖，便会由半固态转成液态墨水，中性笔墨水最大的优点是每一滴墨水均是使用在笔尖上，不会挥发、漏水，因而可提供如丝一般的滑顺书写感，墨水流动顺畅稳定。
