This is a Benesse toy. It's a toy that rolls and encourages babies to crawl after it. Benesse Kodomo Challenge Baby Matte Matte Drum (Around 9-10 months old) Includes "Music Flower" that plays music when the button is pressed. Size: 23 x 17 x 17 cm Acquired around 2015. Works perfectly. No battery leakage. Batteries are not included, please prepare them separately. Please prepare 2 AAA batteries and a Phillips head screwdriver. There are no noticeable stains, but there are some minor stains and scratches from use. I cleaned it as much as possible, but please forgive any remaining small dirt. Please refrain from purchasing if you are a perfectionist. I will sell it to someone who understands that it is a used item. No instruction manual or outer box. Only the main unit is included. #Benesse #KodomoChallenge
