Refillable Marker

grabcad

This pen addresses the issue of markers with low ink levels running out during use, particularly in math classes where students are frequently called upon to write on the board. Traditional refillable markers can be difficult or inconvenient to refill, often requiring a trip to the store. This design allows consumers to easily refill the marker themselves, improving convenience and reducing waste. The tip placeholder indicates that the actual tip is made of paper and sand; dimensions are not to scale.
