Description: 29.5" x 15.5" x 3". It is attached to my front door. the lighting is flourescent but soon to change to leds. there is an extra hinge at the top and a caster at the bottom of the door for support, although it doesnt seem to make a difference. I just have some feeder goldfish in there now. there will be some changes to come for the interior look, but its all about the basic idea, which popped in my head one day.
