Happy Time Glass klein

Crippy, 14mm female, water stained, great function and slow whirlpool drain that is fun to watch. Water staining is present and shown in photos. Otherwise, it is completely invisible when there is water in the reservoir and does not alter the function or form. Hard water stains are calcium and magnesium deposits from dried/evaporated tap water which are nontoxic and simply a visual blemish.
