Compact lubrication

The universal lubricant WD-40 usually comes in a hefty spray can. Even with a fine straw attached to its head, it still tends to overspray messily. For a more precise application of WD-40, use this compact On-the-Go Pen, which applies the lubricant with a focused felt tip, and is the right tiny size for a tool bag, car, boat, kitchen drawer, or bike. — KK
