{"product_id":"the-little-bulwark-kids-thermos-400ml","title":"The Little Bulwark | 400ML Insulated Kids Thermos with Duck-Bill Straw","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp style=\"font-size:18px;font-weight:600;line-height:1.6;\"\u003eSmall Hands Deserve Serious Engineering.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eThe Little Bulwark is a 400ML vacuum flask built from 316 stainless steel, the grade used where corrosion resistance genuinely matters. Double-wall vacuum construction holds temperature for six to twelve hours, which covers a school day from the morning fill to the final bell and still leaves the drink at the temperature it was poured. The duck-billed straw is sized for a child's mouth rather than scaled down from an adult bottle, so drinking is controlled and a spill is unlikely even in a moving car or a crowded classroom.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eAt 7.2cm across and 17cm tall, the flask fits a school bag side pocket and a small hand with equal comfort, and the handgrip shape gives something to hold onto. The cap seals tight enough to travel in a bag without a puddle, and the 316 stainless interior does not hold the aftertaste that lower grades pick up from milk or juice over time. Green, red and pink are available on their own or with a matching carry bag, because the bottle a child chooses is the bottle a child actually uses.\u003c\/p\u003e\n\u003cp style=\"line-height:1.85;\"\u003eA thermos for a child is judged on three things: whether it keeps the drink cold, whether it survives being dropped, and whether the child will carry it. Stainless steel answers the first two, and the duck-billed straw answers the third, because a bottle that is easy to drink from is a bottle that gets emptied. The 6-to-12-hour insulation window is deliberately generous: pack it at seven in the morning and the last sip at three in the afternoon is still cool. That reliability is what turns a four-hundred-millilitre bottle into a daily habit.\u003c\/p\u003e\n\u003cp style=\"font-style:italic;color:#444;line-height:1.8;\"\u003eThis is not a water bottle.
