Refill Leads
There are various types of automatic pencils available in market. These pencils come with extra refill so that the original could be replaced once it gets over. However, the extra ones are limited so for continuous use one need to buy extra set of refill leads. These leads come in a transparent box of 12 or 14 leads of same size. These refill lead packs come in various size and sometimes for specific pencils. They are mostly made by the same manufacturer that has made the mechanical pencil. These refill leads are a cost saving item in the stationery.
