honeycomb (pattern)
A pattern consisting of a series of hexagons lined up together. In nature, this is seen in beehives where bees store their larvae, pollen, and honey.
This tag can be used if you see the honeycomb pattern present on any object, or as a free-floating design (Danbooru post #2276086). If there is only one hexagon present without any others connecting to it, don't use this tag.
