Sharper Image today announced an exclusive collection of FresherLonger Miracle Food Storage Containers (TM), which Sharper Image claims can keep food up to four times longer than conventional containers because of their patent-pending silicone gasket locking system, and antimicrobial silver nanoparticles, a safe antibacterial agent, in the polypropylene material, which reduces the growth of microorganisms. Another benefit: reduced freezer burn, in a container that’s easy to open and close. The containers are shatterproof and safe for the dishwasher, microwave, and fridge. The $69.95 set includes 12 pieces in 6 sizes that conveniently store inside each other.
