New Condition Men's Left-Hand Cobra King OS

4-PW, AW Type, Regular Flex, Standard Length, Standard Lie Angle

Steel True Temper XP 85 Shaft


The Cobra King OS irons were designed with a thinner, stronger PWRSHELL face to give you Cobra’s largest Sweet Zone ever for higher ball speeds and explosive distance. The multi-material Thin, Optimized, and Personalized technology construction allows the CG to be moved lower to create more distance and forgiveness while the CNC milling improves groove structure to deliver maximum spin and trajectory control. The V-Grooves on the 4-6 irons reduce spin, the U-grooves on the 7-PW optimize spin, and the wedge-spaced grooves on the GW-SW product extra spin for shots around the green. The irons have nickel chrome plating that provides better aesthetics and durability to keep them looking great and long lasting.


  • Largest Cobra Sweet Zone EVER!
  • V-Grooves (4-6), U-Grooves (7-PW), and Wedge Spaced Grooves (GW-SW)


Just the wrong clubs

Review by James B., 1 year ago.

“Recently I purchased a set of Cobra graphite irons. Unfortunately they just wouldn’t work for me. I returned the set to 3 balls before the thirty day deadline with no questions asked by 3 balls. I’ve yet to receive my refund to my credit card but I’m sure it will be handled correctly. I thank 3 balls for being such an up front and dependable company to deal with which in this day and age is a rare quality.”
