6. Mugs
Here’s something surprising:
A mug is often an overlooked yet very popular product. In a survey done by the Heinz company, nearly 60% of people said they had an emotional attachment to their favorite mug.

And I bet you can relate to this.
There’s no better way to start a morning without sipping coffee out of your favorite mug.
So, offering mugs with unique designs to your audience doesn’t seem like such a silly idea after all, right?

7. Hats
You can’t go wrong with adding hats to your merch selection.
The reason is simple:
The hat is a perfect accessory that’s equally practical and fashionable. Plus, you can wear the same hat all year long, which again makes it an eco-friendly product:
65% of consumers say they want to buy products that advocate sustainability. That’s why many established brands are moving away from seasonal fashion and going towards clothes that are more versatile and can be worn for longer.

Apart from obvious practical reasons, a hat can be styled to fit any niche or occasion.
For example:
The bucket hat is a very popular choice of streetwear, that frequently pops up on catwalks everywhere. Also, don’t forget that you can also add custom embroidery to a hat and make it a really bold piece.
8. Phone cases
We rarely think about it, but everyone has a mobile phone.
No, really—everyone:
There are about 8.7 billion mobile connections on the planet, against a population of 7.6 billion people.

But is the phone case a profitable product?
In 2022, the worldwide market for phone cases was worth $21.89 billion. It’s projected to keep growing at a rate of 8.3% every year from 2023 to 2030.
So, according to these numbers, you won’t be lacking customers if you decide to add phone cases to your merch selection.
9. Stickers
You can put a sticker anywhere you like: on laptops, guitar cases, bags, hats, coffee tables, etc.
Apart from being popular, smaller items like stickers are much cheaper than t-shirts or hoodies, which automatically makes them a great option for fans who might be tight on cash but want to support you. Everybody wins.

A sticker pack is a must-have product for every brand’s online store. It may not only boost your merch sales but also help your marketing. People who see stickers used by your fans and followers could become a free advertisement for your brand.

10. Face mask
Do I even have to mention why face masks have become such a high-demand product?
Let me just tell you this:
The face mask market is expected to surpass $21.2 billion by 2026.

A lot of brands have immediately jumped on the opportunity and turned this safety item into an unexpected fashion accessory—quite successfully too. Just like any other accessory, face masks are now helping fashionistas worldwide style their looks.
