I don't think it will do anything to harm your health, however a 4B pencil seems an odd shade to choose for eyebrows. An eyebrow pencil may be a more appropriate texture for application and removal.

This are the 6 different pencil cases: '''2B, HB, 4A, 4B, 2A, 4C.'''
A 4B art pencil is a soft lead pencil that produces darker and richer lines compared to harder pencils. The "B" designation indicates that it has a softer lead, which allows for smoother shading and bolder strokes, making it ideal for sketching and drawing. Artists often use 4B pencils for creating detailed illustrations, as they can easily blend and produce varying degrees of darkness.
You can find a 4B pencil at most art supply stores, stationery shops, or online retailers like Amazon or Walmart. Many office supply chains also carry a range of pencils, including 4B. Additionally, specialty art stores often have a wider selection of pencils suited for drawing and sketching.
There is no 4N... 4H = Extremely Hard and will make a light mark. 4B = Extremely Bold and will make a thick and dark mark. HOPE THIS HELPS! :)
If you want. Pencils with higher numbers such as 6Bs give a darker stroke and are softer. So, if you don't mind using a harder, slightly lighter pencil, then go ahead.
That would depend if the pencil were an H or a B. Artist pencils are identified with a number and a letter. H is for hard. A 6H pencil would be harder than a 4H pencil. B is for soft. A 6B pencil would be softer than a 4B pencil.
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
8b - 4b = 4b
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
4b - 1 = -4 + 4b + 3first, simplify and add together what you can.4b - 1 = -1 + 4b4b = 4bbecause 4b is always equal to 4b, the answer is infinite.
A #2 graphite pencil made of wood weighs between 6 and 10 grams. The difference is in the thickness of the wood (cheaper pencils have thinner wood). But it depends on the pencil. There are many different types of pencils that are mainly used in art. There's an HB pencil which is just a regular office pencil, which is probably what you're measuring. But there are also others. There are 2B, 4B, 6B, 8B, and 9B. The higher the number, the darker the color of the lead and the softer the lead. So even though 9B is the darkest color, you'd think it would be the heaviest, but really HB is.
