Thank you for viewing this item. Please be sure to read the profile. [Excellent Condition] MONTBLANC Montblanc Two-Color Ballpoint Pen S-Line Refill Set The S-Line is a slim and elegant design series, different from the current Montblanc. It is a beautiful item with a hairline finish. You can switch between two colors by twisting the metal body left and right. A vintage model from around 1980. It is in collectible condition, which is hard to believe it's about 40 years old. The refills are 4C standard, so they can be purchased at a low price for continued use. I have included the following link as a reference when you want to replace them with your favorite refills. Please take a look if you are interested. *Important information about refill compatibility is listed! https://blog.marswee.com/entry/4c-refill-gokan [Condition] There are no noticeable scratches or stains, but there are some minor scratches and scuffs due to use that are difficult to see in the photos. (Slight, inconspicuous coloring on the logo at the top of the pen.) Please judge from each photo and purchase with your understanding. (No warranty card, instruction manual, box, or accessories.) The original refills are red and blue, but the red one is dried up, and the blue one seems to have about half of the ink remaining. I will include new Jetstream refills, black 0.5 and red 0.5. I will include them as is, assuming you will replace them yourself in the future, so please try replacing them as practice. Remove and replace the refill by pinching and pressing the arrow part in the photo with your finger. (See the arrow part in photo 11) Be careful not to stretch the spring by pulling the refill out forcefully, as it will not return. *For those who are unsure about replacement If you comment after purchase, I will replace them for you. (Example: Please replace both.) (Example: Please replace only the red one with a new black 0.5 refill, leaving the original blue one.) I will also include the packaging of the new refills and the refills after replacement so that you can see the model number at the next replacement. Please feel free to ask. The item will be wrapped in bubble wrap, placed in an A4 envelope, folded to fit within the standard size, and securely sealed with cloth tape, and shipped via Nekopos. Please cooperate with the simple packaging.
