We support any smart, simple invention that could put an eye out, and these TAK Pushpins meet the base requirements. Not only do they have two pins to prevent corner rotation and tearing (a scourge that has terrorized the blacklight unicorn posters of our country for far too long), they also have an arch inside to allow the threading of wire or string. If I'd had these as a child, my thread-and-thumbtack lightswitch rigging might not have been such a bad thing to place over a waterbed.

A six-pack is an all-too-expensive $5, but you can get a pack of 250 for $25.
