A quick search for "pen display case" on AliExpress shows at least three different products in that price range. No idea how deep or wide the pen slots are, though, because I didn't bother to look into the details.
Can you get your hands on an old cutlery box? If so you could order your own pen tray and fit it inside. I bought mine because it was only $40, but it fits 16 pens across. The loops on the top of the case won't fit a thick pen since they're made for utensils, but if you've got some shorter pens you would be able to "stack" them in the tray.
This one came with a felt like liner, and the box is real wood. I'm sure you could ebay yourself and old silverware box. I've never bought from Aliexpress, but it seems like it's just a lot of cheaply made trash.
