## Description

Mr. Pen- 8 Inch Adjustable Wrench, Large Monkey Wrench - desertcart.com

Review: its a wrench - i want to give the wrench itself a 5/5. it sure is a wrench. comes with a cute thank you note too. i want to give Jeffy boy and his AI Ruffy a 0/5. this wrench is, in fact, NOT big enough for my shower head and should NOT have been recommended. but i guess thats on me, as it popped up during my shower head purchase as a "recommended" and thought to myself 'yeah, i dont think i got a wrench big enough' and just clicked add to order. MY mistake. 5/5 wrench. will get plenty of use with my bike, as iv been needing to buy one anyway for the repair kit after loosing my old one.
Review: Works Like a Charm - It is strong and does intended job. the adjustable part could be more stable, but it has good feel, easy to grip, and good for price.

### ⭐⭐⭐⭐ It’s a wrench!
*by B***W on September 2, 2025*

Gave five stars because the item met my expectations in that it was a wrench. The problem is that it doesn’t open up enough for what I want to do. That is my fault not the wrench.
