Can somebody recommend a low(ish) cost eyebrow pencil that I could keep as an emergency spare? I currently use the Mac self propelling crayon one, which is great. However I live in fear of it running about and it often runs out rather suddenly! Usually I have two on the go just in case but I currently don't and it's led me to realise that I should have an emergency alternative that I can just keep in the drawer. God that was long for one simple question! Obviously I really need the help of an eyebrow pencil (thanks, 90s overplucking)!
