GW...send your chips to me and I will look at them closely for about 15 seconds under a jewelers loupe. After that I will scrutinize them under the electron microscope for flaws. Following this I take them to my friend Norman who cleans them while taking a bath. They are now ready to be stored in hermetically sealed zip lock baggies. This takes great care as we do not want them to ever be touched by human hands again. I have found that by adding a little baking soda inside the bag they stay fresher and smell better if ever opened again. You will find that this process is an excellent way to save your chips for eternity so you can never enjoy them again.
