These are Edute building blocks. The ones that make sounds are the 4 blocks with insects pictured on them, the large triangle, the two squares, the yellow rectangle, and the orange block the same size as the bee, for a total of 9 blocks. There are crayon and highlighter marks that can't be wiped off. These were played with by a child. Please check the condition in the photos before purchasing. If you have any concerns, I can add more photos, so please ask before you buy.
