A reusable straw is only worth having if it can be cleaned properly. This brush is a twisted stainless steel wand carrying soft nylon bristles, thin enough to pass through a narrow straw and springy enough to press against the wall of a wider one.
The wand bends, so it will follow a curved straw or a bent tube rather than stopping at the first angle. At 180 mm (7.09 in) long it also reaches into a funnel neck, a teapot spout, a lid channel and the corners of anything cylindrical.
