It’s not often that the automotive industry informs the invention of an eco-friendly home product. Then again, not everyone is Sherri French of spbang, who once worked with cars while living in Shanghai, China. “I was able to take my skills from my ‘day job’ and apply them directly to my own product, using automotive processes and materials,” she says. The bags are durable, and have no traces of lead, BPA or phthalates. Users can even write notes to loved ones on the latest iteration.

Editor’s Note: At first glance, the bags seem small. However, our judges quickly learned that ample portions of anything from animal crackers to bunches of grapes will fit inside. It’s an economic alternative to plastic baggies that easily survives a trip through the dishwasher. Parents who seek practicality and value in products will be elated with this present.
