👉 Booth veins are small, thin blood vessels located just beneath the surface of the skin at the site of a booth or booth stall. They are usually visible when a booth is placed on the ground and the surface is touched or brushed against. These veins appear as pink or red lines due to their proximity to the surface of the skin. They can be used for various purposes, such as measuring blood flow or injecting medications, but they can also be a nuisance if touched frequently.
