This narrow curved dishbrush is made from sustainably harvested coconut and is the perfect tool for cleaning bottles, jars, little grooves and hard to reach angles.  The coconut husk is gentle enough for glass and non-stick pans as well (do a patch test scrub on a delicate item if uncertain).

When the brush is worn, the interior wire holding the husk can be removed with pliers and recycled, while the husk and handle are compostable.
