So, anyone who has spoken to me knows how much I REALLY dig this design. Hello Caps does two variants (most of the time) of this cap. One is the traditional bongo cat, while the other is this artistic and unique design which features the cat as half of a skeleton.  This version of the cap is called Schrodinger bongo cat. For reference:

Schrödinger’s cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935, though the idea originated from Albert Einstein. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects.

With that out of the way, I actually got to speak to Hello Caps about his design with some other friends and I am just in awe.  It’s so creative and the design’s smooth and simple characteristics really allow for the details added to pop and I appreciate how much thought went into this.  This is by far one of my favourite caps in my collection.  This particular cap was themed after Diana from the anime Sailor Moon, which I am a fan of!
