The article discusses the importance of three magnetic containers that are essential packing tools for travelers, particularly in the luggage industry. The containers, which are made from recycled ocean-bound plastic, are sturdy, leak-proof, and work great for a few days' worth of vitamins or holding small jewelry. Cadence is an AAPI woman-owned small business aiming to eliminate single-use travel-sized plastics. The company's founder, Steph Hon, stated that the containers hold approximately one to two weeks of skincare products, more than two weeks' worth serum, two to three days of haircare, and more than 15 tablets. The article also mentions that while the containers are small enough to slip into their toiletries bag and go through TSA with no problem, they are also a useful tool for travelers.
