まあまあ。普通のシャーペンって感じです。 ただデザインは死ぬほどかっこいいです。

クルトガシリーズの中でも安定の書きごこち。ちょっと軽いのが難点だけど書いてるうちは気にならないかも やっぱりアドバンスシリーズが安定ですね ユニアルファゲルスイッチも好きですけど、こちらも同じくらいいいと思います。 あとはもう少しバリエーションほしいのと、重さを出してくれるといいかもしれません

設計製図で愛用。当方男性です。他を4種類ぐらい購入したが、個人的には重さや握り心地など一番しっくりきた。

少し書きづらいけど、シャー芯が折れない。シャー芯が回転しない。

赤色のシャー芯は赤色モデルなど、色ごとに買いました。 カラーのシャー芯はかなり薄く筆圧を上げると脆くすぐに折れます。 結局、ゲルインクボールペンに戻りました。 複数購入しても不良品はなく、品質は安定しています。 使いやすさは昔から変わっておらず、大変満足しています。

I’ve been using the Uni Kuru Toga Advance Upgrade Model 0.5mm mechanical pencil for a bit now, and it’s easily one of the best pencils I’ve owned. The standout feature is the rotating lead mechanism—it keeps the tip consistently sharp as you write, which makes a noticeable difference in how clean and precise your lines look. It’s especially great for neat handwriting and detailed work. The build quality also feels like a step up from standard mechanical pencils. The metal grip adds a nice bit of weight and balance without being uncomfortable, and it gives you a more controlled, premium feel in hand. The grip itself has just enough texture to keep it from slipping, even during longer writing sessions. Another thing I really appreciate is how well it prevents lead breakage. The tip design and internal mechanism work together to make writing feel smooth and reliable, even if you tend to press a little harder. Overall, this pencil strikes a great balance between smart engineering and everyday usability. Whether you’re taking notes, sketching, or just want a consistently sharp writing experience, this is a solid upgrade from your typical mechanical pencil.

Best deal by amazon sg. Shopee / lazada (singapore) are selling at a higher price which is around 1.5 times more than how much amazon sells. Came in original packaging too 👍 The bottom of the pencil is all made from metal and only the top is made of plastic. The weight distribution of the pencil is all close to the tip which makes for a very comfortable writing expetience. Didnt realise how much i love and needed the line consistency from the kuru toga as i tried switching back to my old fure fure corone and immediately hated the big fat line and having to manually turn the pencil to get a sharp thin line only to be back to the fat ugly line in just a few seconds. All these problem are solved here with this pencil and the metal premium feel of the pencil is also what i didnt know i needed too 😂 Writing with a plastic pencil and a metal pencil makes ALOT of difference.

Was a great purchase . Delivered the purchase as I expected with exceptional quality and delivery services . Has sliding sleeve at the tip . Metal grip kinda slides out of hands time to time . Upper plastic body quality was a surprise (very good ). Amazing purchase 8/10 ☺️.

Goed potlood om mee te schrijven maar de 0,3 is wel heeeeel gevoelig wat betreft de druk die je uitoefent met het potlood op het schrijfoppervlak. Kortom in het begin brak de punt met enige regelmaat, je leert niet te hard te drukken. De 0,5 is iets robuuster op dat vlak en voor mij net iets prettiger in de omgang. Het zou ook zo maar kunnen dat de 0,3 meer bedoeld is voor teken of schets activiteiten (of ik ben niet gevoelig of fijnbesnaard genoeg), kortom schrijven kan er prima mee maar met beleid. Potlood voelt overigens prettig wat grip betreft.
