Before purchasing, always consult your vehicle's owner's manual or a professional mechanic to ensure that the Denso IKH16 is compatible with your specific make and model. Incorrect spark plugs can lead to poor performance or even engine damage.

I was skeptical about the "hype" around Menela but honestly it lives up to it. The medium brown isn't too warm (no orange tones!!) which is hard to find in henna. I love that it's vegan/ethical too. Pro tip: make sure you prep your skin really well with an exfoliator first or it might look patchy. Lasts way longer than my usual brow pencil and saves me so much time in the morning.
