Meet urbb - made from biodegradable bamboo, urbb is leakproof, dishwasher safe & has an ergonomically designed mouth spout for a superior drinking experience. Our urbbs are 70% bamboo 15% corn starch & 15% resin. Expertly designed & engineered in Australia, the uniqueness of urbb's design has been formally recognised by IP Australia. The Porter Green team undertook twelve months of research before designing and developing urbb. They settled on bamboo as their main material as it is naturally sustainable, naturally organic, naturally sterile, naturally stain-resistant and naturally durable. Truly a wonder of nature! Available in 3 styles, we hope you love the dreamy and dramatic colours of urbb as much as we do: karistad | coast + storm + dove berlin | night + storm + dove kalahari | reptile design belize | mint +peacock + rain Feautures: urbb | +urban +reusable +biodegradable +bamboo 350ml |12oz leakproof screw lid ergonomic mouth spout | superior drinking experience odourless | flavourless dishwasher safe body | lid - bamboo 70% bamboo fibre |15% resin | 15% corn starch heatsleeve | tab - FDA approved food-grade silicone safe for use from -20 to +110 degrees centigrade presentation - gift box
