It's back-to-school time for many kids across the globe. Parents are helping their kids move into college dorms, people are finding their perfect backpack -- and many of us are finding that sweet, new, and usable piece for our collection and daily life. This time of year is filled with excitement as we enter both a new season -- and of course, school year. Showing off your fandom at school - and even work - is a great way to express what makes you shine! Here are a few of my favorite nerdy back to school accessories, and collectibles, for the classroom and office.

Steven Rhodes Killer Klowns From Outer Space Backpack

Killer Klowns From Outer Space went from cult status to mainstream fandom in recent years. With stores such as Spencer's and their sister store Spirit Halloween releasing new Killer Klowns merchandise and accessories, the movie has been given new life. Certain Killer Klown items can go for serious money. The Laserdisc has sold for as much as $600 on eBay, while the rare VHS with a Klown spinning the Earth routinely sells between $150 - $300.

While this backpack might be on the scarier side for younger people, this backpack is perfect for older teens or adults who need a new convention backpack. This is a large bag too. The dimensions are as follows: 17.6" H x 11" W X 6" D. This bag can hold your ray guns, comic books, and of course, textbooks.

Irregular Choice Charmander Shoes 

While the shoe market may have softened in recent months, unique shoes are still something collectors go after. Combined with one of the most popular video game franchises of all time, you have yourself a hit shoe. Irregular Choice makes some of the best and most unique shoes on the market, and they won't cost an arm and a leg either. Some can become desirable collector pieces too.

These flat, slide-on shoes feature Charmander and Charmeleon -- the two evolutions before becoming the mighty Charizard. These shoes are fun and express your fandom in a keen way.

Super Mario Bros Warp Pipe Pen Holder

If you're a teacher looking to make your classroom more fun, little accessories and decorations can go a long way! This Super Mario Bros. warp pipe is an iconic piece of the video game that is recognized by people all over the world. If you teach elementary school or even college, this fun little piece could help with building relationships with students. If I saw this on my teacher's desk, I'd be more comfortable with them.

Even if you're not a teacher -- or work from home -- this is a fun item to spruce up your space!

Ghost-Spider Water Bottle 

For superheroes big and small, staying hydrated is key. This Ghost-Spider-inspired water bottle is perfect for every Spider-Man (and his amazing friends) fan, especially if your kid is still talking about the two Spider-Verse movies. This bottle comes with a Ghost-Spider neoprene sleeve, but the bottle itself is very eye-catching and just plain cool. This water bottle could be the talk of the playground and office!
