So I'm a bit of an novice woodworker who's taken a class to get me started and only done one or two small projects from there. I recently bought a desk from a seller online and it arrived with a small crack in it. They offered to give me a partial refund to keep it or I could send it back for a full refund. My question is how hard would this be to repair and would it be worth my time and effort?

The crack itself is on the top of the desk surface, right in the front, and it is very jagged (potentially splintery) when running my hand over it. If I were to repair it I would like to repair it so that it blends in relatively well and will be smooth (and structurally sound) when running my hand across. All help is appreciated even if the advice is to just send it back.

Thanks!
