Tired of your fruits and veggies going bad too fast? This ShuRex kit is designed to help. It works in two ways: first, it absorbs ethylene gas – that natural stuff produce gives off as it ripens, which speeds up spoilage for everything nearby. Slowing that down keeps your apples, avocados, lettuce, etc., fresher longer. Second, the activated carbon sachets inside also absorb funky odors in your fridge, so your milk won't taste like onions. The kit includes 2 reusable plastic 'saver balls' (they look like little tomatoes) and 8 refill sachets. Each sachet lasts about 3 months; with 8 sachets, that's a year's supply for both balls. You just pop open the ball, put in a sachet, and snap it closed, then toss it in your crisper drawer. It's a simple way to reduce food waste and save money. Works in the fridge or freezer.
