I usually use the product for arts and crafts documents and decorations. I generally like the product. However I cannot get the 50 sheet package in a thicker Mil. I do use alot of it and I find I get a better deal if I buy the 100 sheet package but it is usually the thicker Mil. product. I find that the staples brand laminator does not laminate the thicker Mil. product as easily or as effectively as the thinner Mil. Product. Both provide a crystal clear nice finish.
