Ugh. This lazy egg seriously can't deal with today. Gudetama can now be easily taken on-the-go with an attached ball chain, although it really doesn't want to go anywhere. The Gudetama Sitting Up Plush Key Chain is made of a polyester blend that is surface washable. Ages 8 and up. Measures about 5-inches long x 3 3/4-inches tall x 3 1/2-inches wide.
