No more plastic in my food
This is the real deal. Get yourself a cutting board maintenance kit and this will last 20 years. Great wood, no micro plastics in your food, easy to clean and maintain. And looks fantastic

Beautiful Acacia Boards That Actually Feel Premium and Thoughtfully Made
I’ve gone through a lot of wooden cutting boards over the years, and these immediately stood out as feeling much higher quality than most sets in this price range. The acacia wood has a really rich, attractive grain pattern and the boards arrived smooth, solid, and well finished with no rough spots, cracks, or cheap “composite wood” feel.
What initially caught my attention was the fact that these are marketed as non-toxic and free from mineral oil. Most people don’t think much about what wooden kitchen products are treated with, but I appreciated that these use a natural blend instead of petroleum-based mineral oil. The boards had a very clean, natural wood smell out of the box instead of that chemical/oily smell some cheaper boards have.
The three-size setup is honestly perfect for daily kitchen use. I find myself constantly rotating between them:
the large board for meal prep and meats
the medium board for vegetables
the small one for fruit, cheese, garlic, herbs, etc.
The engraved food icons are also a surprisingly nice touch because they help keep things organized and reduce cross contamination without looking tacky.
A few other things I really liked:
They’re lightweight enough to move around easily but still feel sturdy
- The wood is gentle on knives
- The groove catches juices well
- They look nice enough to double as serving boards
- Packaging was clean and plastic-free/minimal
Like any real wood cutting board, you absolutely need to:
- hand wash only
- dry them after use
- occasionally recondition the wood
If you expect dishwasher-safe convenience, these probably aren’t for you. But if you want attractive, natural wood boards that feel healthier and more intentional than cheap plastic boards, these are excellent.
Overall, these feel like a genuinely thoughtful kitchen product rather than generic mass-produced boards with a trendy “eco” label slapped on them. Very happy with them so far.

Beautiful in appearance and quality
I've been using these for several months and I love them. They're sturdy and great quality, not to mention so beautiful. They do of course scratch up as you use your knife on them which is to be expected with wood but I plan to give them a little sanding soon and an oiling with the oil they provided. I would definitely recommend.

Ignore the bad reviews, read mine!
Pictures don’t make you think much, but in-person these are beautiful and well made. I’ve been trying to replace everything with cleaner safer alternatives. Honestly I love everything this brand offers and stands for! Some things to think about when you see other peoples negative reviews. Since these cutting boards are all around safe and clean with no toxic coating’s that most have to make them last longer, they do require more maintenance, when people don’t follow that maintenance you get a warped or cracked board. Also they are not meant to last as long as your plastic one from Walmart, they should be replaced more often. Luckily for a pack of 3, and I’ll say again that are TRULY non toxic, they are super reasonably priced! For what they offer I would even pay more for these. They do also come with instructions on how to care for them! So if you are the type of person to leave things dirty, or wet in the sink, these are probably not for you. For anyone who doesn’t mind taking the extra minute these are a must (literally a quick wipe, rinse and hand dry, it’s nothing). Gives me a breathe of fresh air to know I’m using safe, and clean products.

Cutting boards will splinter
A lot of the reviews that are saying these wooden boards splinter are true. I was excited to find some nontoxic wooden cutting boards for such a great price. Upon arrival, they seemed pretty decent quality when I pulled them out of the package. I proceeded to use the large one so I gave it a quick rinse with warm water and was taken back by fumes coming off the cutting board and then wiped it down with a white paper towel and my paper towel was brown. I was a little discouraged, but decided to give it a better rinse with a soap, free brush. At that point once I dried it off whatever coding was on it came off and it was rough and splinters everywhere. Definitely a little upset that the splinters could’ve ended up in our food. These are not good quality non-toxic cutting boards I would rather spend a little extra money on a quality board that is not going to sprinter Wood shavings into my food.
