very brittle but works very good for getting rid of dirt and cal
They arrived fast as usual. I used them to get rid of calcium and urine stone inside the toilets of the house and the shower , it works great u get rid of anything with it but i would not use it on metal surfaces, its perfect for the white ceramic . The only thing and reason why I do not give it 5 stars is that its very very brittle and the last few centimeters actually broke off the stick!
