The word "thumbtack" references the way that these sorts of pins are pushed in with one's opposable digit. This set of Thumb Tacks has been designed so that the pieces truly embrace their designation, having been made into tiny sculptures of fingertips.
The quirky Handy Thumbs pushpins have been made in solid white material and modeled to replicate the appearance of pointer, middle, pinky and ring fingers as well. They're complete with trimmed nails, cuticles and fine lines that mimic the creases of skin, making them quite accurate representations of humans' smallest appendages.
You might actually need to use both your thumb and your forefinger to press the Thumb Tacks into cork boards and pinboards because of their rounded ends. They make wonderfully whimsical accessories for a workstation.
