Dings and scratches on your home’s walls and furniture are inevitable, from kids and pets running around to daily wear and tear. You’ll want to address those small mistakes ASAP, especially if you’re renting, but many touch-up tools are messy and wasteful. Enter: the refillable Slobproof tool that lives up to its name.

Sold in packs of two (or five, if you have more paint colors that need correcting), this handy paint pen can be filled with your own paint to get an exact color match to the wall or piece of furniture you’re fixing. The pen is also vacuum-sealed, so the paint will stay fresh for up to seven years, cutting down massively on waste and saving you from crusty, dried-out paint.

The fine tip, which loads up with just enough paint using a twisting mechanism, ensures precision without leaving noticeable streaks, according to reviewers. “These things work incredibly well. I was worried they would leave weird streaky brush strokes, but they don’t,” one happy shopper wrote. “They’re easy enough to fill with whatever paint you need and they work great for painting over nail holes or larger patches. They also work really well for cleaning up the edges/corners of walls!”

After use, you can rinse off the brush tip for storage and stow it away with the airtight cap until you need it again later. When you run out of paint, you can easily refill it to keep the party going: The set comes with a syringe to insert the paint into the pens mess-free, no pouring required. “Slobproof” is right.
