Genuine beehive, natural product

This is a reverse-bottle-shaped wasp nest that formed under the roof of our laundry drying area.
According to the internet, it appears to be a nest of the Japanese yellow hornet (Vespula lewisi). It is approximately 6 cm in diameter.
We are offering this to enthusiasts.
The nest's structure is such that the brood cells protrude from the bottom of an inverted bottle.
As shown in the photos, it is a nest with a pleasing two-tone color. However, as it is fragile, there are several places where it cracked and peeled when it was removed, as seen in the later photos. The neck of the bottle is also slightly separating, though it is difficult to see in the photos.
We believe it can be repaired using something like Japanese paper (shoji paper).
We will also send any remaining fragments for repair purposes.
We will ship it in a hard case, taking care to maintain its shape as much as possible.
