Good morning, I wanted to know if you have the item for sale that simulates wind noise. It is of cylindrical cardboard with a spring of about 30 cm below. The dimensions are different, in this case the object is high cm. 20 with a diameter of 7, 5 cm It would be better if it were without the ornamental design outside, but only cardboard. I was interested in knowing the price. For the moment I need 500 pieces. Thanking you for your kind attention, send me cordial greetings. Show More
