Brand new, unused item.
I accidentally purchased two of these on Amazon, so I'm selling one.

The following is quoted from the official website:

The MathLink series of math cubes from Learning Resources, loved in over 100 countries. The Numberblocks MathLink Cubes from the UK's BBC's dedicated preschool channel, "Numberblocks," are now available with a Japanese quick start guide and a QR code to view how to play with the activity cards and their Japanese translations! With a guide written in Japanese introducing the globally popular, unique, and cute characters, you can learn math more easily and enjoyably!

For elementary school students, they can be used for basic calculations such as addition and subtraction, as well as multiplication, area, and volume, allowing for long-term and wide-ranging use according to age and grade. After learning, let's foster creativity by building various things with the blocks that connect vertically and horizontally.
