"No Oil" Keychain Tag

cults3d

When you possess a memory akin to that of a guppy and work tirelessly on small engines, you don't want to spark an engine whose oil has been drained and forgotten to replenish. Trust me. To prevent this potential predicament, I have devised these keychain tags that I securely snap onto the key rings of vehicles as soon as I drain the oil, then remove once they've been refilled - a simple yet effective reminder. Book / loose-leaf rings, such as these from Amazon, make snapping them on and off key rings a seamless process, no pun intended... but I'll roll with it anyway.
