Bests & Worsts Reviews from Amazon

As stated in my first review, I thought this was the greatest thing ever UNTILl I was recently breaking down some delivery boxes and instead of taking off the labels like I normally do, I applied the security stamp. I looked and thought this is great how it covers everything. For some reason, it occurred to me that I should look at it later once it dries...lo and behold - I could read every bit of info I was trying to cover. I thought well maybe it's the particular type of material labels are made of so I tried it on a regular letter and a bill - the same thing happened! What a disappointment!!
