ZaKatzDesign has this jumbo Millennium Falcon pin on their Etsy store which the Death Star is removable. A great pin in my opinion.
The pin is 2.56″ wide and is about $75. You can buy the Falcon and pursuing Tie Fighter on its own, if you want, but it’s not quite as impressive.

I was tempted to get one of each version, but decided not to as it would’ve cost too much with shipping and tax to the UK.
Each purchase comes with a free sticker.
Check out his shop as there are a lot of really nice Star Wars designs.
