'WIBIL' is a mobile brand that aims for sustainability and being together throughout kid's growth. While mobile is essential for kid's visual and motor development, the usage period is only a year. Moreover, from our interview and survey, parents tend to change mobile toys in less than a month. Therefore, we have designed a mobile with an extended lifespan that can be played until the age of three by giving a secondary use, toy blocks. We also offer a subscription service where mobiles are delivered according to a child's growth cycle, based on development status data provided by the parents.
