Steel tiered display stand for Hina dolls, 7 tiers, assembly required

This is a dark brown, 7-tier steel rack.
It was originally intended for Hina doll displays, but how about using it for bonsai or other plants?

Dimensions:
??Width: approx. 105cm, Height: approx. 115cm,
Depth: approx. 150cm

??Dimensions of each shelf:
Width: approx. 105cm, Depth: 14.5cm, Height: 1cm

It is about 30 years old, but since it was displayed annually, it is not excessively worn.
However, there are many scratches from use.

The item in the 10th picture is included as part of the set, though I'm unsure of its exact purpose. It will be sent along with the rack. (It seems like it might not be essential.)

The box (cardboard) is aged and has stains and tears.

For shipping, it will be placed in this box and secured with suzuran tape in several places. If you don't mind, I can seal the edges with packing tape.
