Pentel PD105 Mechanical Pencil Review: Japanese Floral Limited Edition Side-Click 0.5mm
Jun 03, 2026
Pentel has a long history of creating mechanical pencils that combine exceptional engineering with beautiful design, and the Pentel PD105 Mechanical Pencil is a perfect example of this tradition. This 0.5mm Japanese floral limited edition pencil features a side-click mechanism and a stunning coloured barrel that makes it as beautiful to look at as it is to write with. In this review, we'll explore what makes the PD105 a standout choice for UK students and stationery enthusiasts.
The Side-Click Mechanism
The PD105's most distinctive feature is its side-click mechanism — a design that advances the lead by pressing a button on the side of the barrel rather than the traditional top-click. This seemingly simple difference has several practical advantages:
- No interruption to writing: You can advance the lead without lifting the pen from the paper or changing your grip, allowing for a more fluid writing experience.
- Cleaner barrel top: Without a top-click button, the barrel has a clean, elegant profile that enhances the overall aesthetic.
- Ergonomic advantage: The side-click position is naturally accessible during writing, making lead advancement more intuitive.
Specifications
- Tip size: 0.5mm
- Mechanism: Side-click lead advance
- Design: Japanese floral limited edition
- Barrel: Coloured barrel
- Brand: Pentel (Japan)
- Compatible leads: Standard 0.5mm mechanical pencil leads
The Japanese Floral Design
The floral design on the PD105's barrel is inspired by traditional Japanese botanical art, featuring delicate flower motifs in a colour palette that reflects the beauty of the Japanese seasons. The design is applied with high quality and precision, creating a barrel that is genuinely beautiful and worthy of display.
Japanese floral designs have a long and rich artistic tradition, from the cherry blossom (sakura) that symbolises the transience of beauty to the chrysanthemum that represents the imperial family. The PD105's floral design draws on this tradition to create a pencil that is both culturally meaningful and aesthetically stunning.
Writing Performance
The PD105 delivers the smooth, reliable writing performance that Pentel is known for. The 0.5mm tip is the most versatile size for everyday writing, producing clean, precise lines that are suitable for note-taking, sketching, and general use. The lead advance mechanism is smooth and reliable, advancing the lead by a consistent amount with each press of the side button.
The pencil feels comfortable and well-balanced in the hand, with a grip section that provides good control without causing fatigue during extended writing sessions.
Limited Edition Collectibility
As a limited edition pencil, the PD105 has genuine collectibility that standard mechanical pencils lack. Pentel's limited edition releases are highly sought after by stationery collectors and enthusiasts, and once the edition sells out, it won't be restocked. For anyone who loves beautiful stationery or Japanese design, the PD105 is a rare opportunity to own something truly special.
Ideal Users
- Students: The 0.5mm tip and reliable side-click mechanism make this an excellent everyday pencil for note-taking and studying.
- Artists and illustrators: The fine tip and smooth lead advance make the PD105 a versatile tool for sketching and illustration.
- Stationery collectors: The limited edition floral design makes this a must-have for anyone who collects beautiful writing instruments.
- Gift buyers: The beautiful design and limited edition status make this an exceptional gift for stationery lovers and Japanese culture enthusiasts.

To get the best from the PD105, pair it with quality 0.5mm leads. The Uni Mitsubishi Hi-uni leads are an excellent choice, offering the smoothness and consistency that complement the PD105's precision mechanism. Both are available at TTPEN UK.
