Sewline Air Erasable Fabric Pen
This pen is unique as it has a 0.8mm ceramic roller ball. This allows it to easily create fine, sharp lines on the fabric. This pen is an absolute favourite here as it is perfect for marking up lines!
The manufacturer advises that the ink will disappear within 2-10 days from most fabrics, and can be erased immediately with water. From experience, the lines often do not last this long, but it depends on the fabrics being used (on polycotton and cotton the best approach is to mark the lines immediately before wanting to sew them).
Ink can be easily erased using plain water.
The pen should be recapped after use and kept out of direct sunlight. Through extensive trial and error it would also be recommended to store the pen upright (lid/nib facing down) when the pen is not in use. This helps to prevent it from drying out prematurely.
Please note, this pen contains Phenolphthalein, a substance with a specific warning in the State of California. Please see the photo of the back of the packet for details on this.
