The product is a lot of virtual electronic Giga Pets, including a Tiger brand Giga Pet from 1997. These interactive toys were manufactured in China and typically required batteries to operate. The Giga Pets were popular among children and collectors for their novelty and ability to "grow" or change appearance based on inputs given by the user. This lot of Giga Pets likely includes various models and may be a nostalgic piece for those who remember these toys from their childhood. Some are in working order. Not sure about all. I did not have new batteries to test all.
