Black CZ Mouse Skates, Ultra-Durable and Low-Friction Crystal Mouse Feet [by SAPPHIRESKATES]

• Mouse skates made of pure cubic zirconia (CZ).
• Incredible metallic-like black color. Highly reflective and still a bit translucent, yet the color is deep and mostly opaque.
• Nearly as scratch-resistant as sapphire (8 on the Moh's scale vs. 8.5).
• Just a bit higher friction than sapphire, but extremely dry and satisfying feel. 
• Slightly lower cost. 
• Comes in 5-pieces per set. Note: does not come with box, but it does come with spare adhesive dots (and adhesive pre-applied as well).

CZ stands for Cubic Zirconia. You may have heard of this crystal before as a cheaper diamond-alternative. Similarly, these CZ mouse skates will be cheaper than our standard Sapphireskates. But don’t sleep on CZ just yet. We selected CZ because it has similar properties to sapphire: 8 on the Mohs hardness scale and just a touch higher friction than sapphire.

In addition, we can offer it in unique colors. CZ can be doped with several elements to infuse a wide range of colors into the crystal lattice structure. We went with an incredible black color: it has a very deep color with a mirror-like finish while still being slightly translucent.

Important notices: although extremely scratch-resistant, you will not want to use sandpaper on CZ as most sandpaper essentially has microscopic crushed up bits of Al2O3 (sapphire) in it.

Another important thing to note: Black CZ Mouse Skates will not come with a box. We will still include a protective capsule, in addition to additional adhesive. But our cost to make this is actually close to Ruby and we want to be able to offer them at a lower price point of $39.99.
