Here in Canada, Zig-Zag rolling papers come in three varieties. White Kutcorners Slow Burning, Silver Ultra Thin Slow Burning, & Blue Kutcorners Free Burning. This review has to deal with what we simply call "Zig-Zag blues". These are my favourite rolling papers bar none. The white's are too thin & rip way to easily while rolling it. The thinness also makes it more probable that the glue will activate itself while in your wallet or pocket as compared to the blues. The ultra thins are literally see through. They must be made of something a little different as they don't rip as easily as the whites, buy it is impossible to find where or if there is even a glue strip on it. The blue are the perfect thickness which also allows for the perfect burn & if you know how to roll, it will never run. One negative is its association with marijuana. Even if you are only using them for tobacco, people automatically assume weed when they see it (such a police or your elders). Compare it to Export 'A' Green rolling papers which is a type of tobacco. Zig-Zag Blue's for life.
