Very pleased with this. However, I did manage to get the ink over myself and my desk! So now I use on a larger piece of paper to keep my desk clean & only put the envelope into the waste bin when the ink has dried. Occasionally it is necessary to stamp 2 or 3 times if the address is larger than usual. Altogether - brilliant - it cuts down the amount of things I have to put through the shredder, and also cuts down on time as I now stamp correspondence and envelopes as soon as I wish to dispose of them rather than saving them up and having to get out the shredder to get rid of 2 or 3 months of papers!
