Bought these because I needed lint free towels for an engine build. They are not lint free. They release lint particles anytime they get snagged on rough metal material or sharp edges like you would find inside engine blocks, main caps, connecting rods, etc. Coffee filters worked better for those parts. These towels worked ok for smoother surfaces without sharp edges like cylinder bores, but they weren’t any better than the Orange big box store painter lint free towels that are a third of the cost and give you three times the towels. For my engine build, I ended up using coffee filters for critical components like main bearings and con rod bearings, and used the big box store lint free towels for other, less critical components because the dispenser box was easier to access. I only ended up using a handful of the ones I purchased here and my opinion is that overall they do not offer the best value ($$).
