The Little Mermaid Water Bottles

Meet the bottle that actually matches your vibe: aluminium, 500ml and ready for whatever your day throws at you. The Little Mermaid water bottles bring playful seaside energy without being juvenile — perfect for anyone who wants a bit of sparkle with reliable performance. Choose from blue, pink or white to match your bag, locker or aesthetic feed.

Whether you're heading to lessons, the gym or the beach, these bottles make staying hydrated feel effortless. The Little Mermaid bottles are designed for real life: compact enough for a school rucksack, roomy enough for a sweaty gym session, and cute enough to sit on a towel at low tide. They look great and fit into everyday routines.

Performance-wise, they’re solid. The insulated aluminium body keeps drinks cold for up to 12 hours and warm for up to 6, so iced water stays refreshing all day and hot drinks hang around long enough for your second lecture or a chilly evening walk. Lightweight and durable, they won’t weigh down your bag but will stand up to everyday knocks.

Style matters — these aren’t plain water bottles. The colours are soft but punchy: that ocean-y blue, candy-floss pink, and clean white all evoke mermaid core without being over the top. If you like vibes that lean whimsical but still mature, these bottles fit the brief. Swap them between friends, match them to your outfit, or make one your daily signature.

We’re small but thoughtful about our footprint. For every order placed, we plant a tree, helping coastal and urban habitats thrive — and yes, you can feel a little proud knowing your bottle helped a sapling get its start. Free worldwide shipping is available (minimum spend applies), so whether you’re local or overseas, getting one to your door is simple.

These bottles make great gifts, festival companions, or study-desk essentials. They’re practical enough for busy weekdays and cute enough for weekend plans, bridging function and fun in a way teens and young adults actually appreciate. Swap single-use plastics for something that’s fresher, reusable and responsibly minded.

If you want a bottle that brings mermaid energy without the fuss, this is it — stylish, sturdy and sustainable. Grab your colour, pack it into your daily routine and enjoy a bottle that keeps up with you.
