I don't have a measurement (.006, .008, etc) and I just looked, no thickness on the box just says medium thickness. Like I said, I like medium for turkey and heavy for goose. If you google search dental rubber dam you will find it is popular as a sex accessory for some. Makes it too expensive to buy if available at all. Wholesalers and dental supply will not sell to an individual. Talk to some local dentists, tell'em you're a turkey hunter and would like to buy some latex. I keep mine in the bottom of the refrigerator out of the light and heat, lasts a long time. The sheets come in 5x5 and 6x6 with around 50 sheets to a box depending on thickness, company, etc.
