Neat item!
This "bundle" had a large collection of art; a little something for everyone.  These disks worked well.  There is a protecting cover that has to be peeled off of each disk.  This is easy to do.  I would be careful of the edges of the disks as they are rather sharp.  I may sand them down a little.  Younger children should be supervised due to the sharpness.  All in all, a good product at a good price.
