Hello, my name is Julien from Germany. I am actually searching for O-Rings out of 100% pure natural rubber in size 25mmx1,5mm. There should be no other chemicals added in the O-rings. They should be in natural rubber color ( yellow and transparent). First of all i need some production samples, after checking the quality i intend to purchase regularly about 10kg per month. Please get in touch with me, if your company is able to produce the O-Rings. You can contact me here jwypich1990@gmail.com Show More
