Troublemaker fountain pen inks are known for their bold character, expressive color palettes, and distinctive shading that transforms every page into a work of art. Handmade in small batches in the Philippines, these inks have developed a devoted following among writers and artists who appreciate something a little different.

From soft, moody pastels to rich, saturated tones and complex multi-shaders, Troublemaker inks offer a dynamic writing experience that evolves as the ink dries on the page. Many colors reveal subtle undertones, gradients, and unexpected shifts, making them especially popular for journaling, sketching, and creative lettering.

Made with Tsubame's elegant cream fools paper*, each memo block consists of 400 pages with a thick cardboard divider at the 200 page mark (so you can easily split the block in half to create 2 blocks of 200 pages each).  Paper size 3.35" x 3.35" (85mm x 85mm).

*Fools Paper (or OK Fools) is a high-end Japanese writing paper, famously used in Tsubame's notebooks - it's designed to be exceptionally smooth yet fast-drying for fountain pens. Originating as a superior alternative to imported British Foolscap in the 1940s, it is known for being non-feathering, bleed-resistant, and having a slightly cream color that is easy on the eyes.

The TWSBI Classic Sapphire fountain pen pairs timeless design with modern fountain pen engineering.
