Please Note: We recommend using Waterman Inks with this pen. The use of other modern inks, or inks with shimmer, may hamper the filling system and writing qualities of the pen. Also, if you use pen flush to clean your pens, make sure to use a non-ammonia based solution, since ammonia based solutions will not only shorten the life span of latex diaphragms and sacs but can also damage solid gold nibs. The use of inks other than what we recommend or ammonia based pen flush, will void any warranty that we offer. If you have any questions, please contact us.

**Vintage pens, or pens marked as Pre-Owned will be considered for return only if they arrived to you as mechanically defective. These 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, which means that they will be finer than western counterparts (e.g. Japanese Medium is more like a Western Fine, Japanese Fine is more like an Western Extra Fine, etc.).
