Where QB Smart Series Shines
Tech & Devices
QB Sticker — iPads, school-issued Chromebooks, laptops, and Nintendo Switch consoles. Kids love stickering their devices, so a smart sticker feels natural.
QB Tag — Headphone carrying cases, charger pouches, and portable battery bags.
Sports & Activities
QB Tag — Musical instrument cases, sports duffels, soccer bags, and dance/gym garment bags.
QB Sticker — Bicycles, scooters, skateboards, and helmets. A sticker on a helmet is highly visible if left at the park.

QB Tag — Soft lunch bags, winter coat zippers, umbrellas, sleeping bags, and summer camp luggage.

Manage Your Tags →Born in the Bay Area,
Made for Dreamers
QBFun started with a simple idea: everyone has an inner child who deserves a little fun, creativity, and something truly theirs.
What Makes Us QBFun
Radically Personal
No two products are identical. Every mug and tag we make carries a piece of someone's story.
Garage-Made Pride
We press every single order ourselves in our Bay Area garage studio — with care, precision, and a lot of love.
Inner Child Energy
Whether you're 6 or 60, we believe the best designs come from embracing playfulness and imagination.
How It All Started
What began as a way to press our own kids' drawings onto mugs quickly turned into something bigger. Neighbors, friends, and family started asking — "Can you make one for me?" And so QBFun was born. Today we're building a little corner of the internet where creativity meets community, right here in the Bay Area.
