I've had this on my "Wish List" for over a year now and this is absolutely the cheapest I've found it at in that time. Sold! I didn't want to write a review until I'd actually started using it and I'm really impressed - I knew I would be after the research on reviews I'd looked at online. It lives up to all the claims and I'm really chuffed that it fits my glass palette perfectly (which was a cheap glass kitchen board from Amazon). Like the old Tupperware (for those of us that remember it ????????), there are loads of points of "click and seal", that once you've finished going around it, you absolutely know it's airtight. To make the paints last even longer, I've popped a couple of drops of clove oil on a cotton bud in a little bowl in the corner. My only problem is, it doesn't fit in my freezer!
