Do not buy from TCP Global Corp because of excessive shipping charge. I bought two PreserveIt cans at the good price of $5.30 each but they charged $15.00 shipping making the net cost $12.80 each. Retail price in an art store is roughly $7.00.When you buy multiple products at one time, Amazon makes it difficult to identify how the shipping charges are allocated. One has to be vigilant for companies such as TCP Global Corp that advertise a low price and then tack on an outrageous shipping charge.PreserveIt is a good product for adding some degree of resistance to smudging for art work. I use it on laser printed book covers. The gloss version is a bit smoother than the matte, but I have used both types with satisfactory results. Sumdging is less of a problem but can still occur with a greasy finger and strong pressure.
