Review on Cal Hawk AZGA125 Grommet Assortment Electrical: Complete your Electrical Projects with Versatile Grommets! by Michael Welborn

Good material, thick rubber but not as rubbery as we would like. It was more like soft plastic. The size and varieties are good but not very helpful for you to know which size is which square. A grid with printed sizes would be much better. Next time I'll just write down the exact jacks I need because I've found that I don't have enough jacks of the size I need and I had too many jacks that I never used.
