A handy good quality brush to fit in the bottles. Hadn't thought of one before but with my eco swaps this is a good one!
This brush is perfect, does exactly what you need it to. Have had it a couple months now and is still in great condition. Will be a permanent switch from plastic brushes in my house!
Would love to be able to buy a replacement head for it!

Small and useful. The end uncurls to reach around corners.
