Esthepro Integrated Circuits Silicon Wafer Made by Copper Process (12 Inch)

I have work experience in semiconductor manufacturing and they are exactly what you would expect. (check them out under a microscope for a really cool view!) If you see that it's a greyish color that's completely normal for this kind of wafer. (Just get it under a light and tilt to the right angle for display if you want to see the rainbow reflections.)

I love mine got it as a Xmas gift last year been hanging on my wall in my game room ever since great conversation piece and teaching tool i am blown away with quality will Buy a few more to add to the wall soon

Looks beautiful and is well packed for a safe delivery.

Bf loved it

Beautiful piece of silicon have ordered multiple for crafts and have been happy each time!

My wafer arrived well packaged and intact. The package would need to be mishandled badly to break the wafer. I also want to point out that the frames that are used to display 12-inch LP vinyl records (and picture disks) are a great choice for displaying the 12-inch wafer. Mine was one of the higher-priced frames available here on Amazon, so I can't vouch for every cheaper frame sold here, but the size of the round hole in the matt is perfect. https://www.amazon.com/Picture-Record-Frame-White-Solid/dp/B00V3UOM8C?ref_=ast_sto_dp

Love it. All my life I have worked in the I.T business and having worked with computers all my life it's nice to have this as a souvenir.

First time I ordered, wafer and box arrived damaged and broken into many pieces. Not good. Second time I ordered, box was good but wafer was shattered. Not going to waste time on a third order.

Awesome-looking wafer, a great addition to a room design. Shiny!
