This is a replica of the Global Communicator link like they used on Earth Final Conflict . Their are no electronic and their are no moving parts . It is a closed unit and the screen will not pull out . It is made of a solid resin . Great for display or autographs .Please contact me through ebay only, my email hasn't been too reliable lately and I have no idea what is wrong with it. I'll check the My Messages folder daily :) Shipping is 8.00 US and Canada. Overseas shipping is 26.50 because I now require a signed confirmation of delivery because I've learned the hard way t are those who I just have to protect myself from. We have other props we will be listing soon!
