Jim,

Thank you for the info on the Luxor UV markings, I saw these chips and I segregated them and wrote labels on them but my "guests" cannot see the markings then I have to put out the UV light out to show.

I wish someday down the "slippery road" there will be a special plastic page that you can house the chips and it will show the UV markings on each chip without using the UV light.

I am right now looking for a pen light or flashlight used by the "dermatogist" as portable set on top of my working table.

I enjoyed looking at your "innovation" on the EXTRA now in use.

More power to you.
