Complete set of multi cavity injection molds , fabrication and automatic assembly equipment for the manufacturing of two ball point pens and three markers including a double ended one with roller ball and highlighter combo. All the molds and the equipment were made in USA and are located in California USA. All pen caps have breather channels and are child proof. The reason for the sale is the high cost of labor in USA . As an example , the stic ball point pen assembly machine produces 22,000 pens per 8 hours with one operator, hot stamp printed if needed, but still it is hard to compete with the low cost imported pens in USA.
