What is it? A friendly little competition

Happy Wednesday, lovely readers! Today I'm bringing you a fun little challenge. Ok, it's not really challenging, and there are no real prizes, but I thought it would be fun anyway.

It all started when I took the following picture. Obviously I know what it is, but I've had fun over the last few days trying to get people to guess what it is:

Can you tell what it is? Watch, I'm sure now that I've opened it up, someone will guess correctly in two seconds! But if you have a guess, leave it below in the comments. And heck, if it takes long enough for someone to guess correctly, maybe I can figure out some sort of prize...
