A review for Rounded corner stickers by daniel schroeder.
the proof was sent right away after I placed my order, and it was even better than my own cropping. the stickers are of fantastic quality, and it's hard to not just keep them for sticking all over things.
overseas shipping was outrageous, though... $40 to ship 50 stickers is ridiculous. it's definitely going to keep me from ordering more in the future (at least while I'm living outside the US).
