Cassiopeia, Milky Ways Youngest Supernova Keychain
Galaxies, Stars and Nebulae series This extraordinarily deep Chandra image shows Cassiopeia A (Cas A, for short), the youngest supernova remnant in the Milky Way. New analysis shows that this supernova remnant acts like a relativistic pinball machine by accelerating electrons to enormous energies. The blue, wispy arcs in the image show where the acceleration is taking place in an expanding shock wave generated by the explosion. The red and green regions show material from the destroyed star that has been heated to millions of degrees by the explosion.

Dear Zazzle representative,
I highly complement the metal keychain received which appears more attractive than the photo on website.
There’s one question I wish to ask. Is the leaf 🍀 in the keychain a genuine leaf?
It’s colour and contextual are more realistic than one I see in the nature.
Yours sincerely,
Catherine. The outfit of the keychain is excellent. I just wonder if I’ve mistaken the four leaf clover inside the keychain is genuine a leaf? Or is it a printing of the leaf which looks so real?

Oval Metal Keychain
Absolutely thrilled with my customized keychains! The photo of my Yorkie came out clear, the colors are vibrant & the quality is fantastic - it’s sturdy + well-made. Just ordered another one for my mom. Thank you to the Artist, Jenn, for creating such a beautiful piece! Highly recommend!

Rectangle Metal Keychain
Creator Review
I honestly wasn't sure what the quality would be like, but I was pleasantly surprised. It's a pretty solid key chain. After use for a few weeks, it's held up well. There are minimal scratches on the silver parts and none on the printed areas. I think this is going to make the perfect gift for some of my friends. Although I do think I'd personalize it with an initial. The printing is great. It looks exactly like the photo. Not quite as shiny as the metal, but really looks nice.
