I will be going home for the New Year's holiday, so I will be selling items until December 26th. I will be lowering the prices slightly until then, so thank you for your understanding. This is a HOZAN crimping tool (for ring sleeves), crimping pliers P-77. It is compatible with the electrician's skill test, and the applicable ring sleeve sizes are small (1.6 x 2) / small / medium / large. I purchased this for the electrician's skill test, but it doesn't fit my hand size, so I am selling it.
