I got my OXO good grip container in a 1.7 qt size and I love it.  I love baking and use a lot of walnuts, pecans, and pistachios in my baking so I buy them in bulk.  Only problem is they taste stale if not stored in a good airtight container.  That is where this wonderful airtight container by OXO comes in handy.  I decided to use it with my pecans and I am so happy with it that I have ordered a couple more in larger sizes for my other nuts.  The airtight seal works great.  It is super easy to use.  Just push button down for airtight seal and push again to release the seal.  Very happy highly recommended it.
