Description Diamond Ink Chemical Writing Fluid in large 32oz bottle. Fantastic label showing an eyedropper fountain pen. Interesting text on front label indicates, "Writes a bright blue changing to a permanent black gives one copy if taken soon after writing. This is a true chemical fluid which does not fade." Near perfect front label, and smaller label on back of bottle has a small piece out of it. Cork has shrunk so would need to be recorked if you wanted it to fit snugly. Exceptional bottle not often found. **Vintage pens, or pens marked as Experienced will be considered for return only if they arrived to you as mechanically defective. Experienced pens may have small defects or scuffs, since they often have been pre-owned, and they have been priced accordingly. All Japanese Pen Nibs are graded as the manufacturer intended, that is, they will be finer than western counterparts (e.g. Japanese Medium is more like a Western Fine, Fine is more like an Extra Fine, etc.).
