Review on 🔧 KOOTANS 1200Pcs Nitrile Rubber O Ring Kit: Complete Set for Plumbing, Gas, Automotive and Faucet Repair - Resist Oil & Heat by Aaron Ethridge

These o-rings come in convenient metric sizes in increments of 6mm to 28mm and I use these nitrile o-rings on my fingers to seal my many rings (jewelry) in it to keep place and safe. They work great for me without the hassle I've experienced with other inferior brands. I've bought them 5 times already, I've had great results and success with them. They work better than I expected for me and my "weird" usage. I would highly recommend them to others as they have not given me any problems. very satisfied and thanks to this seller for offering them at a reasonable price. :)
