You've got a pair of VGR Voyager hair clippers and trimmers there, which are popular for their "transparent" industrial design and digital displays.
​Based on the image, here is a breakdown of what you have and how to maintain them:
​The Gear Breakdown
​The Clippers (Teal & Black): These feature a digital LED display that usually shows the battery percentage and a refill icon to let you know when the blades need oil.
​Guide Combs: You have various sizes (measured in mm or inches). These snap onto the blade to control how much hair you cut.
​Maintenance Kit: The small brush is for clearing out hair clippings, and the clear bottle is clipper oil—the most important part for keeping them sharp and cool
