Air takes out the freshness, EVAK takes out the air! The longer your food is exposed to air, the faster it loses flavor. Glass containers with air-tight lids are readily available, but they trap stale air in with your precious food. Evacuate the air and keep your food fresher and longer with EVAK glass storage containers by Prepara. The twin valve system automatically forces the air out as you push down the lid, and allows you to easily pull up and remove the lid to access contents. It"s so simple- just push down, then pull up; no buttons or levers. Perfect for coffee, tea, cereal, dried fruits, granola, herbs, spices, confections, etc. There are other food storage containers that remove the air but are made from plastic that comes in contact with your food. With EVAK, only glass and stainless steel contact your food: no harsh plastics. EVAK Is made from the highest quality borosilicate glass and stainless steel, and they are the only parts that come in contact with your food. The handle is made from super- strong ABS plastic with LFGB European grade silicone gaskets on the inside. EVAK Was launched on Kickstarter and is the winner of the 2014 Red Dot Award for Product Design, the 2014 IHA Innovation Award (International Housewares Association) and a 2014 Idea Award Finalist (sponsored by Industrial Designers Society of America). To use, simply fill glass base with dry goods for storage and press handle down to the level of food, air is automatically removed through the valves. To remove, pull handle up. Simple care: base is dishwasher safe, twist off stainless steel cap and hand wash handle.
