A genius and most definitely not a rip-off of the trashy underwear brand Calvin Klein. Originated from Georgia on October 3rd, the superior brand “Kelvin Clein” was born from the mind of a sleep-deprived, seriously stressed out high schooler who’s mind wandered about the similarity between Kelvin (temperature) and the Calvin cycle

Get the Kelvin Cleinmug. He keeps bossing around; he always thought he was the main character, and he always comes back whenever he has no one to talk to

Get the Kelvinmug. Kelvin is an amazing person, sweet and compassionate about things he cares about. Kelvin is very smart, even though he acts like he's not, and he's adorable beyond anything you could ever imagine. He is the funniest person you can meet and will make you laugh until your ribs hurt. He gets angry when people call him Kevin, and when he gets mad, he gets MAD. Never get on Kelvins nerves or you're in for a treat. Overall a Kelvin is someone who always looks out for his friends and has a girlfriend who loves him very much. If you ever meet a Kelvin in your life, make sure to hold him close and never let him go or you'll lose someone who is a extremely good friend and amazing boyfriend.
