This is a Formula one Tire Stack Pen/Pencil Holder! It can also be used to hold smaller mechanic tools such as screwdrivers. It's the perfect gift for any F1 enthusiast or mechanic! There are three different tire profiles: wet, intermediate & slicks. The tires will always be black unless otherwise requested. The top colour can be be customised, this is the secondary colour in the listing. 3D printing does come with some imperfections, however, to ensure customer satisfaction I will never dispatch an item that I would not be happy to use. Unfortunately, I do not accept returns. Thank you for browsing, I look forward to printing your order! ATTRIBUTIONS: Remixed the below into pen cups.
