You can rent a small place in front of the building materials to show it. I have seen such sales, but I don't know how effective it is. Mainly depends on whether the rent is appropriate. The customer base is used by people who have just finished decorating their houses to decorate their new houses, or to open an aquarium store for direct in-store sales. The key to wall-mounted publicity is to avoid changing water, which is a selling point or on-site maintenance for reference only.
