The first thing to know is that cigars should stay in a humidor (the first syllable rhymes with you, as in the word humid) until they're ready to be smoked. When necessary, you can get away with keeping properly humidified cigars in a sealed plastic bag with a small, damp paper towel for a day or so.

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's CRT display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy.
A marker is an ink-filled pen with a wide tip. Kids often use washable markers, while adults are usually trusted with the permanent type. Permanent markers contain ink that can't be washed away, and they're useful for labeling and marking things like cardboard boxes and file folders. Another kind of marker is a highlighter, which you can use to make important words or phrases in a book stand out with a line of translucent neon ink. A different meaning of marker is something that marks a route or specific place. Markers along a hiking trail help keep you from getting lost.
