- The ink in this Sewline pen has been specially formulated to stay visible for up to five days. (The speed at which it disappears depends on the humidity in the atmosphere.)
- In addition, it features a smooth-rolling ball tip which enables you to mark fine, even lines and create smooth curves.
- Stays visible longer.
- Smooth, even lines.
- Easy to trace curves.
- Lines can be removed with a shot of steam or wetting if so desired.
