Avogadro's constant: "the number of elementary entities per mole of substance". It's a big number...which is to say, there's a lot of stuff in the universe. Wear a piece of it with this hand-stamped tie bar.
Available in aluminum or bronze, it is sturdy enough to last a lifetime. (Note that hand-stamped lettering varies a little, so yours will be charmingly unique.)
I ordered a tie bar and received it only 2 days later...in plenty enough time for our last day of school gift exchange! The gift was well received!
Avogadros constant tie bar
Other than needing a spring instead of straight across, keep having to adjust. It is great, conversation starter for sure!!!
Avogadro would be proud
Excellent product, ordered from the UK arrived less than a week
Great Tie Clip
Bought this for my husband as a present in the gold/bronze color. It is a gorgeous color and we were both very happy with the quality of the product. He loves it. It arrived quickly and in a beautiful box. I would definitely recommend this company and product.
Excellent gift idea!
Thank you for the wonderful ideas you design. They make great gifts and are so appreciated by my friends.

I want to wear it to a Job interview. I saw it on The Big Bang Theory television show.
My first time ordering from this website and I am very impressed. The necklace is beautiful and arrived in a timely manner. Thank you Boutique Academia your professionalism and attention to scientists/math lovers! Will purchase from here again.
I love my tardigrade buddy! I got the vertical one on the long chain and it is just amazing and so cute (and noble and smart, my goodness possibly charming as well). It has a brilliant solid weight & is quite lovely in its pose. It is smooth and I love to hold it as well as it just looking cool around my neck. Shipping was super fast, communication was good, and packaging is nice. All the stars.
