BRAND NEW IN 2020 DIRECTLY FROM THE ORIGINAL BOXES !
ALL 10 OF THE ORIGINAL BOXES WERE TOSSED BECAUSE THEY ARE NOT HEAVY ENOUGH TO PROPERLY PROTECT THE MOTOR DURING SHIPPING. THEY WILL BE RE-PACKAGED IN A MUCH STRONGER BOX FOR SHIPPING. Please note that the tachometer(in the pictures) has 1 decimal position on the readout when reading slow rpm"s
Please note that none of the extras that are seen in the photographs are part of the sale. For clarity the sale is for one GREARTISAN gear motor only.
EXTRA CARE IS TAKEN NOT TO BEND THE LEADS THAT COME OUT OF THE MOTOR. THEY ARE NEW AND HAVE NEVER BEEN BENT OR FLEXED.  THE MOTORS WILL BE PACKED IN SUCH A WAY TO PREVENT ANY UNDUE FLEXING OR BENDING OF THESE LEADS.
IN THE BOX THESE WEIGH 15.7 OUNCES WITH THE BUBBLE WRAP. 16OZ. IS THE LIMIT FOR 1ST CLASS SO IF YOU BUY MORE THAN ONE THEY WILL GO PRIORITY MAIL.  THAT IS WHY EACH ADDITIONAL UNIT IS .00 SHIPPING. iF YOU BUY SEVERAL WE ALWAYS REFUND EXTRA SHIPPING BACK TO YOU WHEN WE PRINT THE SHIPPING LABEL.
