Good for studying
Format: Hardcover
I like that the book has large margins on each page to add notes. I'm sure you don't care about this review because you have to buy it for a class anyways.

Definitely a Must-Have
Scent: Sandalwood
This beard kit is legit. The sandalwood scent is clean and manly without being overpowering, which makes it great for everyday wear. The oils and balms actually soften coarse beard hair, reduce itch, and leave the beard looking healthier and more manageable. Packaging feels premium and the pump bottles are easy to use — no mess, no waste. I’ve tried a lot of beard kits over the years, and this one hits the sweet spot for quality, scent, and value. Highly recommend if you want a well-groomed beard that doesn’t smell like “baby powder mixed with perfume.”
If you have facial hair, you’ll notice a difference after the first use. Worth every penny.

Works great & smells good!
Scent: Sandalwood
I was concerned the facial wash would be too harsh but thankfully I was wrong. Every part of this kit compliments the other. My skin and beard feel noticeably softer, and I haven't had any acne breakouts. The scent is masculine but not too strong. This is now my new routine.
