## Description

The Uni-ball Eye Needle offers precision writing that gives you complete control over ink placement. The ballpoint pen contains smooth-flowing pigment ink that is waterproof, fade proof, and tamper proof. It is built with a strong, durable needle tip that won't break or bend under pressure. The ink pen is ideal for taking short notes, working on lengthy projects, or technical writing. A 0.5mm nib creates ultra-fine, unbroken lines, and the comfortable grip is great for left or right handed users so you can keep writing all day long. A capped top completes the rollerball pen, ensuring that it stays put and will never leak in your pocket. Blue Ink in a Box of 12.

Review: Un'ottima penna sotto tutti i punti di vista, anche se il tratto e' piuttosto fine. Sarebbe auspicabile avere di nuovo disponibile la UB-187S Eye Needle, con ago di 0.7 invece di 0.5
Review: sur 12 rollers seuls 3 d entre eux ont marché plus de 5 minutes .... ou j ai reçu un lot douteux non vérifié ou c est une arnaque totale !! comme je fais du dessin en noir et blanc je me rends compte vite fait !! avec les 12 j ai à peine pû faire 3 dessins en format A3 alors que d habitude avec un roller sans marque j en fait au moins 3 ou 4 .. MAIS comme déménagée en pleine campagne j avais pensé qu au lieu de me déplacer je pouvais commander sur internet et soit disant une marque réputée !! bref ....première et dernière fois

The pens were delivered in a package different from the photo. Not a big problem. The problem is that the first 2 pens stopped writing after 1-2 pages (see the photo). Probably, I received the pens from a defective shipment as a Uniball pen I used before was perfect. Thanks to Amazon for returning the money.
