I feel that this product is a rip off at nearly $2 more than the same product from [...]. In addition I can still very clearly see my checks through the security tint. What's the point of paying extra for the tint?!This is the first time I have bought self-adhesive envelopes so I cannot compare it but it seems to seal well enough since I don't put much in the envelopes.I am still incensed at paying so much extra for the same product. If I wasn't in an emergency and had to use an envelope right away I would have returned it!
