When you think about it, every writing implement we use depletes the harms the environment in some way – pencils use up wood, disposable pens use plastic, and even refillable pens create waste. German design company Jac Zagoory Designs is bringing back an age-old method of writing with metal to create an eco-friendly writing instrument.

It’s called the Beta Inkless Pen, and instead of ink it uses lead to create lines on almost any paper surface. It never needs to be sharpened, refilled or replaced – although since it’s made of lead you might want to be a bit careful about where you place it (don’t chew on the tip while you’re thinking of your next sentence).

The Beta pen is surprisingly affordable for a pen you never need to replace – just $27.95 for the full-size version or the keychain version. The lines won’t smudge or erase, and it works in any temperature. And maybe best of all, it’ll never embarrassingly leak in your shirt pocket.
