Irrational pi Hairpin

When your hair is feeling irrational, pin it up with one of these pi themed hairpins.

These are great hairpins for pi day, March 14th.

Key Features:

• Hilbert Curve Finish: 80% density on top/bottom layers for a premium, textured feel with added grip to prevent the pin from sliding out
• Easy Multi-Color: Designed for simple layer-swaps. You don't need an AMS to make this pop--just a bit of patience to do the manual filament changes.
