Frank Green 1L Colour-Changing Ultralight Bottle in Lava with a Flip Straw Lid (Personalised)

Make hydration feel a little bit magic.
The Frank Green 1 L Colour-Changing Stainless Steel Bottle isn’t just clever — it’s pure fun. Watch it shift from a vibrant yellow to red as you fill it with icy-cold water, then fade back as it warms. Every sip becomes a little show, sparking smiles at school, the gym, or on the go.

Crafted from over 95 % recycled stainless steel, this ultralight bottle carries more with less weight, making it perfect for daily adventures. The Flip Straw Lid offers easy one-hand sipping and leak-proof confidence — whether it’s in a backpack, handbag or work tote.

And with personalised laser engraving done right here at Creative Kids Lab, every bottle becomes uniquely yours. Add a name, emoji or icon for a sleek, permanent finish that stands up to everyday use — no stickers, no fading, no mix-ups.
