Eyebrow product I have been using consistently and well

This is the Beyond Stay Long Auto Eyebrow Pencil in shade 01 Black Gray.

I usually use gray or black-gray shades to match my skin tone, and this is a product I bought by chance that I’ve been using well. I’ve used it for so long that the wear and tear is incredible. I just looked it up and it seems to be discontinued, so I’ll have to think about what to buy next. Often, even products labeled as "black-gray" don't capture the gray tone well, but this one is versatile and not too dark, making it great for naturally filling in and drawing eyebrows. I love this product because after shaping the eyebrows, you can gently blend them with the brush at the back for a natural finish.
