Shelf life of Matsui pigments

[Rockers]

Just found 6 x 1Liter bottels of Matsui pigments in our shop which I had totally forgotten about. If I'm not mistaken they date back to 2007, a good 6 years. What's the shelf life of those pigments if there is any at all. Would be a shame if they are off, lot's of fluoro pigments that would have to go in the bin otherwise.

I'd think as long as they were sealed well, no worries. Double check/test for color before using in production though.
