“The Perfect Gift. KING INN 3D”

 

I have not seen this gift case before and it is very attractive. Does anyone know what the extra space is for? (Where I have the transformer cable in the pictures)

 

The viewer uses fluorescent bulbs and has a switch that switches from front lighting to back lightning so you could use it either for prints or transparencies.

 

I have not been able to test the optics since the slot is for 132x80mm slides and the only ones I have around here are in 140mm mounts and they do not fit.
