Frank Green Twilight 740 ml Colour-Changing Ultralight Bottle — Flip Straw Lid (Personalised)

Make every sip feel a little bit magic.
The Frank Green 740 ml Colour-Changing Stainless Steel Bottle transforms before your eyes — its bright purple exterior deepens dramatically when filled with icy-cold water, then fades back as it warms. It’s hydration that’s as playful as it is practical — made for school, work, gym or everyday adventures.

Crafted from over 95 % recycled stainless steel, this ultralight bottle blends premium quality with planet-first design. The Flip Straw Lid makes sipping effortless — leak-proof, one-handed, and ready for any backpack, tote or lunch bag.

And just like all our favourites here at Creative Kids Lab, every bottle can be laser-engraved with your name or icon — a personal touch that means no more lost bottles or mix-ups, just a stylish, sustainable bottle that’s all your own.
