Slurp. Sip. Sustain. While your teens are enjoying their favorite beverage with this Buildable Wheat Straw Kit, they will also enjoy the fact that they're doing something good for the earth at the same time. Composed of reclaimed stalks from wheat and a bit of plastic, the kit includes a 9" wheat straw, a wire cleaning brush, and a protective travel case. The straw unscrews into three pieces, and the 4 1/4" brush fits inside the straw to create a compact set that fits neatly inside the travel case. The case includes a carabiner clip for easy attachment to clothing or a bag, which makes this reusable straw kit the perfect on-the-go accessory. The harvested wheat that makes up most of the pieces is sustainable and renewable - and the reusable straw helps keep turtles and other wildlife safe - so this straw kit is the perfect eco-friendly Prom favor, Homecoming dance keepsake, school store supply, or school fundraiser. Whether they're slurpers or sippers, your teens will feel good about doing something good every time they use this reusable straw set.
