While many of you know us for our laser engraving, we’ve recently expanded into CNC machining. One of the first products we created was actually something we needed for our own golf cart. After a few people asked if we’d sell them, we decided to make more—and they’ve been selling faster than we expected!

Our CNC-machined lithium charge port adapters for E-Z-GO golf carts are now in stock and ready to ship.

Thank you to everyone who has supported Foster Customs. We appreciate every order and look forward to bringing more products like this in the future!

It's been months of designing & redesigning, but I am excited to launch our new hanging led signs. The LED lights we use are amazing & controlled using an app. The designs can be created by me or logos can be provided. All signs come with 2 ways to power, battery or USB cord. https://fostercustomsco.etsy.com
