Hi, this is a used but in very good condition MATCO GRBLM1313 - 13mm - 12 point double box (box & ratcheting) wrench. It is the smaller one of the two pictured below
* Double box configuration - has both breaking end and ratcheting end
* Forged for increased strength
* Slim head profile that fits in tight spots
* 72 tooth pawl for 5 degree swing arc - versus 20 degrees like other ratcheting...
