Details:

• Sea urchins have played an essential role in the ocean’s ecosystems dating back hundreds of millions of years.

Stemcell opened in Tulsa, OK in 2016. They believe a better world is just one idea away. As fans of science, they thought there should be a place to shop for scientific supplies and goods, so they created that shop. Nothing fascinates people quite like science. It's like real magic!
