These display identification acrylic cubes are great for putting next to an item in a display case where there are several items that are similar. But the number will identify what it is at the podium description sign. These are 3/4" solid acrylic polished cubes that are laser engraved and color filled with a standard white color. If white is not your color we can do whatever color you want. We also do identification cubes all the way up to 4" square. The standard set is 1 - 10, but can go up to 50 if necessary. We do these for museums all over the country, all different sizes, colors and numbers. Just message us for any requests or questions. Thank you for shopping with us at PlasticMart.
