Do they love cooking and have lots of veggies out at once? Bigger engraved cutting boards with a juice groove would be best.
Is it a wedding gift,
and you want to give something that will last for decades? Choose a
higher priced, brand name board that looks amazing with your custom
laser engraving (all bamboo boards will last for years and years when
cared for, I've had the same boards for 6+ years and they look the same
as when I bought them!)
