This thing is just ok. I've had it barely over a week and only stamped about 5 letters and the ink is already looking kinda tired. There's a little plastic window piece on top of the stamp that shows what the stamp is (i.e. the window snaps shut and holds in a square piece of paper with "RETURN TO SENDER NOT AT THIS ADDRESS" written on it so you don't confuse it with other stamps) and that window has already broken off and won't snap back into place. So my verdict is that if you buy this plastic thing that is cheap, you're getting exactly what you should expect: a cheap piece of plastic.
I mean... it's OK i guess?
