It’s bamboo and sisal, it’s a brush.
It’s getting rather hard to name them now.
It fits in your mug perfectly and will be smashing for washing up.
Made from bamboo (super stuff) with sisal bristles, you can get those pots and pans shining like a new pin!
It will last ages and look good in the process!
When it finally gives up the ghost, the old one can be composted, put in the wood burner, or recycled at your local recycling centre.
