U=ma²... what does it MEAN! maybe as a adherent guinea pig of Agnes Tachyon you should know that, or maybe you should watch Umamusume: Beginning of a new Era and find out!
Unlike the hypothetical FTL particle, this one can be observed with the human eye.

Amazing quality and comfortable fight, the color is fire and the design in super cool. Definitely get your uma cap from this store!

A good quality hat, just like what the other reviews had said. Just took a little bending on the brim to get it more center and not crooked.

Very nice quality, the quality was good mesh with the letters standing out nicely. Has a very clean look. Took a little time to arrive but got here.
