I am I interested in the round black tube insert with collapsible rib design. I need 1 & 1/4 inch inside diameter and 1 & 5/8 inch outside diameter. I'm sorry I don't know how to relate to your measurement. Do you have them to fit this size? If so, In what quantity and price?
We have a 42mm round tube insert that takes a wall of 3-5mm.Our minimum order quantity is 100pcs and the price is, $0.4354 each. We currently have stock of this size. Please let me know if you would like a sample for testing and I can post one to you. You can contact me directly on, firstname.lastname@example.org.
