Choosing the right pen is a small detail that makes a big difference. Whether guests are signing a traditional guest book, a signature poster, or writing over fingerprint art, the ink should look clean today and hold up beautifully over time.
For the best balance of smooth writing, lasting ink, and a guest-friendly tip size, our top pick is the Sakura Pigma Micron 05 Pen.
Our Top Pick: Sakura Pigma Micron 05
The Sakura Pigma Micron 05 is the pen we recommend for most guest books. Its archival, pigment-based ink is designed for long-lasting writing, while the 0.45 mm tip creates a clear signature that feels substantial without overpowering a page or piece of artwork.
It is especially lovely for:
- Traditional wedding and baby shower guest books
- Signature guest book posters
- Fingerprint guest books, once the ink-pad print is dry
- Messages, names, and dates you want to keep readable for years

Three Pens Compared
1. Sakura Pigma Micron 05: Best Overall
Why we recommend it: archival pigment ink, dependable black color, and a smooth medium-fine line that works beautifully for both quick signatures and longer notes. It is our clear favorite for a keepsake guest book.
2. Uni-ball Signo: A Good Backup, With a Few Caveats
The Uni-ball Signo has a comfortable grip and a pleasing gel-ink feel. However, gel ink can take longer to dry, which raises the chance of smudging when many guests sign in a short window. It can also be less predictable on textured paper or on top of an ink-pad fingerprint. If you use one, test it first on the exact paper and let every fingerprint dry completely.
3. Regular or Fine-Point Sharpie: Skip It
We do not recommend regular Sharpie permanent markers or standard fine-point Sharpies for a keepsake guest book. They are not archival choices, can bleed or show through paper, and may create a heavy mark that distracts from the artwork. For signing over fingerprints, they can also make the details feel crowded.
A Simple Setup for Guests
Place one or two Sakura Pigma Micron 05 pens near your guest book and keep the signing area easy to spot. For a fingerprint design, add your ink pads and an instruction card nearby, then remind guests to wait until their fingerprint is dry before writing their name.
That is all you need: a thoughtful guest book, a great pen, and a place for everyone to leave a little piece of themselves behind.
