In serious need of suggestions!

My fiancé and I didn't get to spend Christmas together so now I'm rushing to try to find him something. When I asked him what he wanted he said things like nice pens, (he's a writer) or something to put on his desk, he's a huge philosopher nerd and I'm completely lost. Under 60$ would be good since we just splurged on a big vacation last month. All help is welcome! thank you :)
