ForeverPen™

Most everyday-carry kits have room for a pen, but few pens are built to stay there indefinitely. ForeverPen™ is pitched as exactly that: a very small writing tool that clips onto a key ring or slips into a pocket, with no ink supply to run dry.

Writing without ink

According to the maker, ForeverPen™ relies on a special material rather than conventional ink, removing the need for refills or replacement cartridges. The campaign frames this as a pen designed to be used permanently. The source does not identify the material or describe how its writing compares with an ink pen.

Built for the key ring

The maker describes the pen as extremely compact and says it is made from high-quality, durable materials intended to withstand drops and impacts over long-term use. It is also described as TSA-compliant, which the maker says should let it pass through airport security checks while travelling.

• Ink-free writing that the maker says requires no refills
• Extremely compact size for attaching to keys or carrying in a pocket
• Durable construction described as resistant to drops and impacts
• TSA-compliant, according to the maker

The Kickstarter project raised roughly $2.46 million from 54,857 backers, according to the source page.
