Cylindrical Rollers importer for cylindrical rollers - Clothing - Fashion

I've search your rollers and notice you note that you can provide various rollers. I stand for Hiwin and from Taiwan. I'm wondering if you can produce these small specs, such 3*4, 4*5, and 4.5*6.5. I have inquires for three different types, but I don't know who I can reach to get more details. It would be highly appreciated if you can pass my email to the right contact person.
