This is a Oster 4937 Coffee Grinder Accessory, still in its original packaging. This versatile accessory is designed to attach to any Osterizer Blender or Kitchen Center Appliance (blades and bottom cap not included, as stated on the box) to transform it into a powerful coffee grinder. It's perfect for grinding coffee beans to your desired consistency, from coarse to ultra-fine. Beyond coffee, it can also be used for grinding spices, bread crumbs, making sauces, relishes, dips, and even baby foods.

The accessory features a durable, break-resistant plastic container with a convenient storage cover, offering a one-cup capacity. Its clear design allows you to monitor the grinding process. Proudly made in the USA, this accessory is an essential addition for any Oster appliance owner looking to expand their kitchen capabilities.
