This Penco Portable Bullet Mechanical Pencil is great for travel. When capped for storage, the length is only about 95mm (3.77''), so this compact size will easily fit in even the smallest carrying packs, and can also be comfortably carried in your pocket. However, when the cap is posted on barrel, the pen transforms to a full length pen of 130mm (5.11"), which makes it feel just like a normal pencil when used for writing. These Bullet Pencils comes in a compact storage size but still gives the writing experience of a full sized mechanical pencil. 

• Uses 0.5mm mechanical pencil lead; comes with pencil lead pre-loaded. 
• Sturdy but lightweight.
• To secure the cap on the barrel, press the cap into the barrel until it clicks.
