Our Neutron Star fountain pen ink bursts onto paper with a sparkling array of blue and sheening iridescent purples, pinks, and reds with Twinkle pigments. Visible coloring will vary drastically by paper type and saturation, with high quality fountain pen papers producing secondary colors most prominently and lower quality papers staying closer to the ink's base blue hues.

Our swatch and writing sample is produced on 68gsm Tomoe River paper, which strongly emphasizes the secondary colors specifically (making our samples look purple on camera.) It's very difficult to display the color array of sheening inks on-screen.

Twinkle inks require additional pen maintenance and cleaning compared to their traditional ink peers and perform best in a pen with a medium sized nib or broader. Please don't use Twinkle inks in vintage pens or pens that cannot be disassembled for cleaning. 

Every batch of Birmingham fountain pen ink is manufactured by hand in-house from a series of raw ingredients selected for quality and consistency. Each bottle is poured, capped, and labeled by hand.

International & U.S. Territories
As we work to navigate the quickly growing list of international tax complexities involved with retailing to customers in many countries, our current international shipping options are very limited. All international shipping rates are calculated live at checkout based on weight and destination, shipped by UPS or USPS. International customers are responsible for any customs, tariff, brokerage fees, etc. that may be assessed. Inquire with your relevant local governing agencies for details.
