Black hole triangle sticker
Black Holes Have Simple Feeding Habits At the centre of spiral galaxy M81 is a supermassive black hole about 70 million times more massive than our sun. A study using data from Chandra and ground-based telescopes, combined with detailed theoretical models, shows that the supermassive black hole in M81 feeds just like stellar mass black holes, with masses of only about ten times that of the sun. This discovery supports Einstein's relativity theory that states black holes of all sizes have similar properties.

The quality of this product was perfect for what we wanted. The printing quality was perfect but the print was just outside the the sticker so I contacted Zazzle and I must say, I had excellent customer service! The error was on my part as I did not see the "safe line" for printing but Zazzle very kindly refunded my account so I could re-order the labels correctly. Would highly recommend this site!

I needed arrows for a D.I.Y. "mini bowling alley" made up of foam tiles with a wood grain pattern. I didn't want to use a marker so I tried these. They do the trick! Nice solid black color. Does not smear when handled.
