Great quality cutting boards set
This set of cutting boards is very well made and looks beautiful in the kitchen. The wood is sturdy, smooth, and easy to clean. I really like that it comes in different sizes, which makes it convenient for preparing vegetables, meat, and cheese separately. They are not too heavy but feel durable and long-lasting. They also look nice enough to use for serving snacks or appetizers. Very satisfied with this purchase!

Oil them often
Beautiful boards. Wish the charcuterie side had more sections in the smaller boards. Be prepared to oil them often or the cut marks show quite a bit.

Just what I expected
Been using these for about a month now. I will say they do scratch very easily. My knives suck, and first use you can see every scratch. I don’t really mind because I feel like that’s expected with wooden cutting boards.
They look pretty, sit pretty, and haven’t split or warped on me yet. They have a good weight to them as well. I imagine you will have some upkeep such as using oil/board butter but I haven’t gotten to that point yet.
