Each cube has a unique number and color, a different one being obtained each time the player opens the gift. This item is quite rare and normally sells for a high price.
The cubes can be opened 79 times, each time changing color, and getting smaller by a fraction. On the 80th opening, the cube will disappear.
Here, you will find the number and color that goes with each number.
Shrine of the Sight
On January 7, 2017, it was discovered that the changing of colors on the cubes are not random. There is a pattern for how the color changes, each pattern is unique for the 25 different numbered cubes. When recording the color-changing pattern of a cube 80 times, the different colors can be organized into an 8x10 area to create a portion of a pixelated image.

The usage of the Numbered Cubes are to open up the Shrine of the Sight. The key for how to open the shrine is below.
