A pack of 6 Refill Nibs for the the Sewline Aqua Eraser and Liquid Eraser Set. 

The Aqua Eraser is perfect for removing drafting lines from fabric without hurting the fabric. It works rather like a fountain pen with a reservoir you simply fill with water or a water and detergent mix.

Your finger pressure on the soft grip then dampens the special soft fibre point. By lightly dabbing or running this point along the line or mark, the special point absorbs the pencil or water-based ink mark.

When the point of the Aqua Eraser becomes discoloured, simply replace with a new point.
