Great quality natural brushes to replace plastic
Been swapping out all the plastic junk for natural items. These brushes are great, I use them with dish butter and they work great. So far holding up really well. Plenty of brushes for different needs, we even have a dedicated veggie scrubber now.

Not Bad
This is how the item arrived. The bristles may be a little rough, but if you are expecting this organic alternative to resemble the same convenient quality as plastic or a sponge… I don’t know what to tell you.

Great Set of Brushes for Variety of Needs
Excellent set! Very pleased! You even get an extra head with the dish brush. Sooo much better than plastic imitations! The smaller dark bristled brush is pretty stiff, not sure I would use in my job stick pans, but makes a great veggie cleaning brush! Between variety of brushes, you can reach very thing in variety of situations and shapes! Absolutely love them!
