The image shows four long, cylindrical tubes hanging on a white wall. The tubes are arranged in a row, with the first tube on the left, the second tube in the middle, and the third tube at the bottom. Each tube has a label on it with a red and white striped label. The labels appear to be made of glass and have Chinese characters written on them. The background is a plain white wall, and there is a shadow of the tubes on the right side of the image.
