Hello, I would like to get a quote for inner tubes sizes 10", 12", 14" and 16". It can be for bycicle, scooter, motorcycle. Also, In how many colors can you produce them? Can you reproduce custom shapes like two or three tubes one on top of the other? (See picture) Can you produce them with elastic fabric covering the rubber so it does not deform when you inflate them? A very important factor is that it does inflates evenly, including around the valve. Please replay as soon as possible.
