Here’s an ideal office accessory, the Ninja Tacks, which give the impression of a Ninja throwing star embedded into your message board when you pin something up with them.

The Ninja Tacks were previously only a concept, but they have now gone into production and you can get yourself a set for $12.

“Ninja Tacks are thumbtacks designed to give the illusion that throwing stars are embedded in a surface. This product is an informal re-imagining of an often overlooked essential office tool.”

The Ninja Tacks are now available from chromoly.
