Generally, it’s best to use a ballpoint pen or a pencil when working on wooden materials. One of the main reasons for this is the porous nature of the wood material. Of course, gels work too. But, that’s only if you let the ink dry for a minute after writing. Once you make sure of this factor, you can go ahead use gels from the classic black and blue to glitter, erasable and white. Just, make sure that the models you pick work best with woods.
