The Nib Safety Net

"Gravity Happens. We’ve Got You Covered."

We know the heartbreak of a fountain pen hitting the floor. As a member of our Creative Rewards, you don't have to worry about the 'tines.' If the worst happens, just send us a photo and we'll send you a 50% discount for a fresh start.

"The Nib Safety Net" – Terms & Conditions

  • Eligibility: This benefit is exclusive to active members of the Creative Rewards program at the time of the accident.
  • Coverage: The 50% discount applies strictly to accidental damage (e.g., dropping the pen) that renders the nib unusable. It does not cover intentional damage, loss of the pen, theft, or normal wear and tear.
  • The Claim: To activate your discount, you must provide a clear photo of the damaged nib and your original order number to oops@yourstore.com.
  • Limitations: This discount is valid for a one-time replacement per pen purchased and applies only to the cost of the replacement nib unit. It cannot be combined with other promotional codes or used for full pen replacements.
  • Availability: We will provide the discount for the exact nib model where stock is available. If the model is discontinued, we will offer a 50% discount on a comparable alternative nib unit.

The accessible Japanese benchmark

Iroshizuku occupies an iconic position in the stationery community: accessible and reliable enough for daily notes, yet visually rich enough for fine calligraphy and art journaling. The dye-based formula is heavily lubricated to ensure your nib glides across the page without hard-starts or skipping, drying quickly compared to other saturated inks. Every tone is an explicit color argument inspired by changing seasons and landscapes—*Tsuki-yo* captures the deep blue-green of a moonlit night, while *Kiri-same* reflects a soft autumn rain. The heavy, hand-blown 50ml glass inkwell features a deep, V-shaped interior well to ensure smooth, mess-free filling down to the last drop.

Colour taken from Japanese nature

Iroshizuku joins two Japanese words: iro, colour, and shizuku, a droplet. Since Pilot launched the range in 2007, every colour has been named after something in the Japanese landscape or seasons — moonlit nights, autumn showers, deep sea, a lantern glowing in the dark. They are dye inks with a smooth, well-lubricated flow, and they have become the benchmark many fountain pen users judge other inks by.

Honest Note:

Iroshizuku is a dye ink: it is not waterproof and will run under any wash, so it is not for linework you plan to paint over — use Platinum Carbon Black, Kakimori or De Atramentis Document ink for that. It is designed for modern fountain pens; if you have a vintage pen with a latex ink sac, ask its restorer which inks they recommend. The 15ml bottle is a sampler size — it does not have the 50ml bottle’s filling recess, so large nibs may need a syringe towards the end.

Who is it For?

  • Fountain pen enthusiasts who want a premium Japanese ink with wide availability
  • Beginners wanting their first premium ink — safe, reliable, and well-reviewed
  • Writers who want well-behaved inks with Japanese nature-inspired colour names
  • Anyone who wants a colour they can rely on in any fountain pen without concern

FREQUENTLY ASKED QUSTIONS (FAQ)

Which colour should I start with?

Tsuki-yo (blue-green) is the most loved; Shin-kai is a classic blue-black for work; Syun-gyo is the one to try if you want a black with personality.

50ml or 15ml?

15ml to try a colour or carry a travel bottle; 50ml for a colour you already love — it costs less per ml and has the deep filling recess.

Is it suitable for illustration?

For linework that will not be painted over, yes. Under washes, use a waterproof pigment ink.
