This engagement ring set, below, was spotted for sale on the streets of Akihabara, and includes a ring advertised as being appropriately sized for 1/6 scale figures.
Perhaps it is aimed at the novice otaku who will not go as far as marrying a 2D character, but will settle for a girl that is at least partially 3D?
The yellow ad reads:
A plan for “My Wife”!?
A engagement ring for use with 1/6 dolls!?
The larger ring is for your own use♥
One concern that comes to mind would be the excruciating process of deciding which figure in one’s collection to put the ring on…
