Schaff Ebony Black Piano Caster Cups Set of 4

I liked the product and that is why I have ordered it. I used for what it is intended: cups for piano casters. I have just had my living room carpet pulled out and exposed magnificent hardwood floors that had to be sanded (a nightmare) and refinished. I did not want to take any chances, hence cups under coasters. I was not even aware that such a product existed. I was looking for inspiration, and as soon as I entered what I needed, websites started popping up.

Great quality and felt on the bottom. Fits our baby grand piano perfectly.
