although we have purchased the o-rings for different purpose, quality appears to be good. Moreover sellers response was excellent as he replaced the initially delivered O-rings with different size based on our requirements. Very good communication and follow up by seller through whatsapp and call.

Good quality, I just wish they were a more complete sizing option where the sizes didn't skip from one to another
