The Little Mermaid Tumblers

Say hello to beachy vibes in cup form. These Mermaid-themed tumblers bring seaside energy to your daily routine — whether you’re heading to school, a shift, or just lounging with a playlist. Fun Cases keeps it playful and practical: bold prints, rainbow gradients and subtle shell motifs that give each sip a little bit of ocean magic without feeling tacky.

If you’re hunting for The Little Mermaid tumblers, you’re in the right place. They’re designed to stand out in a crowd of bland drinkware, weighing in at a generous 40oz so you can stay hydrated all day. The patterns are bright but wearable, perfect for people who want their accessories to feel like an expression of personality rather than a flex.

Functionally they’re solid too. These 40oz insulated tumblers have a sturdy handle and a straw, built Stanley-style for iced lattes, smoothies and long study sessions. The double-wall insulation keeps drinks cold for hours, and the leak-resistant lid makes them commuter-friendly. They’re big enough to last through classes, shifts and gym sessions without constant refills.

For those who search for The Little Mermaid travel cups, these are your go-to. Compact enough to fit in a backpack side pocket, yet roomy enough to replace multiple single-use bottles, they hit the sweet spot between portability and capacity. The straw and handle combo makes them ideal for on-the-go sipping — walk, skate, or bus it with your favourite drink in tow.

Made with a vibe that’s both retro and modern, these tumblers pair well with stickers, lanyards and charm clips if you like to customise. They’re great for gifting to friends, for uni flatmates, or as a treat for yourself. The designs are curated to suit anyone who loves a pop of colour and a touch of mermaid fantasy without being over the top.

We care about the planet as much as you do. For every order placed, we plant a tree, helping to give back to the places that make summer and seaside memories possible. Plus, we offer free worldwide shipping — minimum spend applies — so you can get your cup delivered without surprise costs.

Cleaning is easy: pop the lid parts off, give them a rinse and you’re good to go. Our community of buyers often shares photos and tips on style combos and sticker layouts, proving these cups are as much a fashion statement as they are practical.
