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!”AmazonThe pen is easy to use and refill, so you can paint over all the dings on your 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.“I have white walls and white trim and 2 dogs and two kids. I’m constantly touching up paint. These are AMAZING. I have every color in the house in one of these labeled. Genius idea!” a reviewer shared.Parents love it. Airbnb owners love it. Teachers love it. Furniture sellers love it. You get the picture. Below, check out some promising reviews for this bad boy and add it to your cart — you can get years of use out of this and fix up your home again and again for under $20.“Because it was inconvenient to open a paint can and use a brush for a small touch-up I tended to wait until I had a number of dings to repair. Then, invariably I would forget a spot or two and I never really kept up with the repairs. However, now the Slobproof pens are so convenient that I can touch up a paint issue as soon as I see it. Clean up is easy in the sink because the amount of paint on the brush is minimal. I keep three pens ready with my different colors including one for white trim. This really is a clever product that works very well.” — Tim“If you own or rent a place, you need this touch-up pen. All you have to do is put the paint in and touch up your little boo-boos....its really worth having.” — SNOWDIVA“Life saver for small dings. I used this to repair some small wall dings and this is the greatest. I was able to fill with my own paint so the color was an exact match. Doesn’t leak, they are super durable and only had to fill once or twice to get through my whole home. The cover made it great for going back through the house and finding more areas. When I asked my husband what he thought he said it blended so well he couldn’t even tell where I used it. Best value for money if you are trying to fix up your home!” — amazon12“I received the pens today and within 30 minutes, had one filled with paint and using it to touch up the cabinets. This handy little thing is a game changer for me. Kudos to the inventor. Getting the big can of paint and the brushes was a pain so I’ve always procrastinated about touching up cabinets (especially shoe molding) and baseboards but now, there’s no excuse. The syringe is very easy to fill but remember to slowly inject it into the pen and wash the syringe immediately afterwards. The soft little brush is also great for touching up the top “lip” of the baseboards and not getting it all over the wall.” — Tonya Lanahan “Love these! I sell furniture and always include one of these touch up pens! Easy to fill and use! And they don’t leak!” — Katherine A HeikausThe original version of this story was published on HuffPost at an earlier date.Trending In ShoppingMore In Shopping
