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 Serious Collector's Standard

Col-o-ring was created specifically to solve a cataloguing problem the fountain pen community ran into when a previously favoured Japanese flashcard product was discontinued. The result, developed with a paper specialist, uses 160gsm acid-free European paper rigorously tested to resist feathering, bleeding, and show-through — performance that matters when judging an ink's true sheen and shading characteristics. The split-ring binding is the other key feature: individual cards can be removed, reordered by colour family or brand, or added to indefinitely, rather than being fixed in book order. Reviewers with very large ink collections (some maintain 400+ swatch cards) confirm this remains practical at scale when paired with binder sleeve pages.

Honest Note:

This is positioned as a more serious, technically-focused tool than a decorative swatch card — the plain chipboard cover and utilitarian card design reflect that purpose. For a lighter, more visually charming everyday cataloguing option, see the Wearingeul Ink Colour Swatch Cards instead.

Who is it For?

  • Serious fountain pen ink collectors who want maximum paper performance for judging true sheen and shading
  • Anyone testing inks with dip pens or sharp nibs, where the paper's resistance to nib damage matters
  • Collectors with a large or growing archive who want a reorderable, expandable cataloguing system rather than a fixed book

FREQUENTLY ASKED QUSTIONS (FAQ)

Can I use a dip pen nib on this paper?

Yes — the paper is described as slightly toothy but not enough to catch even the sharpest dip nib, making it safe for both fountain pens and dip pens

Does the paper show sheen accurately?

Yes — this is one of its strongest points. The card stock is thick enough to resist bleed and show-through while still revealing sheen clearly once the ink has dried, particularly in areas where ink has pooled slightly.

Can I add more cards later?

Yes — the split ring binding allows cards to be added, removed, or reordered at any time, so the book can grow with a collection rather than needing to be replaced.

How does this compare to the Wearingeul cards?

Col-o-ring's heavier 160gsm paper and rigorous feathering/bleed testing make it the stronger choice for serious ink testing and sheen visibility. Wearingeul's cards are a lighter, more decorative option, well suited to everyday cataloguing rather than technical testing.
