Sailor Pen Recycling factory Fairline 3 Work hard (3-color ballpoint pen)

"Fairline 3 Work Hard" is a 3-color ballpoint pen with a neck strap that has a built-in black ink replacement core that is often consumed.
The ballpoint pen can be hung from the neck, which is very convenient to use immediately when you want to use it.
It is very practical because it saves you the trouble of putting it in your pocket and you don't have to worry about it falling off, so it is ideal for work sites and people related to medical care and welfare.
In addition, the strap has a safety design that will come off when a strong load is applied, so even children can use it with confidence.
A frequently used "black" spare core is built into the shaft to eliminate ink shortage during use!
