A three-piece wooden musical instrument set that includes a drum, guiro, and bells.

They hit, shake, and scrape the instruments shaped like circles, triangles, and squares.
You can experience the joy of producing different sounds depending on the instrument, how hard you strike, and where you strike.
The round part of the drum has small balls inside, so you can shake it to enjoy it.

The sticks are thin enough that they are easy for small children to grasp, making them a great choice for children just beginning to show an interest in things.
Of course, it can also be used for parent-child communication.
