This is a set of (2) cell towers.
One tower includes a base station created form a 20 ft container with electric meter and disconnect on it.
The towers are assembled in pieces and one can be made taller while the other is made smaller, as shown they are about 9" tall.
When assembling if they do not slip together easy, use a hobby knife (xacto knife) to clean out the holes.
Inside the hole, as they are so small, there could be a tiny amount of uncured resin. If the knife blade has resin on it after cleaning out the whole just clean it off with a paper towel and throw away, it is such a minor amount that it is not a concern.
