Periodic Table Poster - Large 24x36 inch Ultraboard with Wall Standoffs - STEM Science Classroom and Lab Chart created by college professors in Dallas, TX

Too close to Christmas to return it, poorly protected packaging with a bent corner. But ultimately, they punch dime size holes in each corner (unlike the Amazon photo image displayed above does not have them) to give it spunk so it floats off the wall. Not so grand, due to the holes destroy the integrity of the imaging imo. It’s so light, why punch holes when you can easily use Velcro strips to hang it. I wish I didn’t go by the photo above, if I knew it had holes I would not have bought it obviously.

I loved the colors and the quality of the paper. I was able to clearly read the letters and see the images without any issues and is made with a high quality material. It's Beautiful, clear, easy to understand with Condensed information on a single chart and most importantly it's up to date. Was perfect for my classroom. I use it for straight Chemistry.

Amazing periodic table and fantastic service.
