Plain Tumblers

Plain tumblers from Fun Cases are the low-key flex your day didn’t know it needed. These 40oz insulated cups come with a sturdy handle and a straw, Stanley-style, so you can haul hydration through lectures, shifts, festivals and late-night study sessions without constant top-ups. Tough enough for backpacks and concert mosh pits, sleek enough to match your aesthetic — minimal vibes, maximum mileage.

Built with double-walled insulation, each cup keeps ice intact for hours and your hot drinks pleasantly warm when you need them. The handle makes one-handed sipping a breeze and the straw feels effortless for commuting or chilled hangouts. Yep, they’re big — but that’s the point. No more running to refill between classes or gym sets; one fill gets you through.

We kept the design simple so your cup can be whatever you want it to be. Pick bold colours, soft pastels or matte neutrals to suit your everyday look, and swap stickers, charms or a personalised sleeve for extra personality. The plain canvas of these tumblers is perfect for customisation — team colours, fandom decals, or just your name scrawled with a permanent pen.

Looking for a fuss-free option for travel and commuting? Our Plain travel cups combine the portability of a traditional travel mug with the capacity of a 40oz tumbler. They’re ideal for long journeys, road trips and days out when you don’t want to waste time hunting for a café. Lightweight, leak-resistant and ready to tag along on every plan you make.

Being chill about style doesn’t mean being careless about the planet. For every order placed, we plant a tree — a small but steady way to give back and make your daily sip part of something bigger. Plus, we offer free worldwide shipping (minimum spend applies), so getting your new favourite cup to your door is easier than ever.

Whether you’re into morning coffee rituals, iced concoctions or plain old water, these tumblers handle it all. They’re dishwasher-friendly in most cases, built to last, and designed to be the kind of thing you grab without thinking. Low drama, high function — perfect for routines that are equal parts hectic and fun.

So if you want a reliable sidekick for class, work, workouts or weekend adventures, a Plain tumbler from Fun Cases is ready. Grab one, make it yours, and keep sipping — with less waste, more style, and a tree planted because you ordered it. Simple, useful and made for the days you actually live.
