Simple yet effective
Format: Paperback
This book is incredibly effective. I enjoyed how everything was easy to understand and how it uses simple terms. Learning that money is about our behavior changed my perspective. I would recommend this book to anyone who is 16+ and interested in getting a head start on how to be smart with money!

So Adorable! Thicker Paper and Fun to Color!
Format: Paperback, Format: Paperback
The Coco Wyo team has done it again! Another super cute coloring book filled with the cutest characters! The paper is thicker than in previous Coco books, yay! but if you’re using markers you will still want to put paper behind the page you are coloring. Ink bleed through still happens but not as much.
Shading:
If you want to add shadows on top of the marker areas, the Prismacolor premier soft core colored pencils work beautifully, but be sure to let the paper dry completely first.
Update Review Regarding Marker Blending:
With the thicker paper you can get away with many rounds of normal blending techniques with both alcohol markers. See the photo of mine with the shooting star. That page has so many layers of marker blending that I lost count, haha and the paper is still in tact! Yay!
Creating Highlights:
I use Sakura gelly roll pens as well as acrylic paint pens for highlights with no issues.
Pro tip: If you’re using gelly roll pens, be sure they are bold 10. That will fit the scale of the art on the page and it won’t get clogged during use.
Coloring Tools:
I’ve tried using:
Copic alcohol markers
Tombow water based markers
Ohuhu alcohol markers
Kingart water based markers
Kagito alcohol markers
Prismacolor Premier Soft Core colored pencils
Sakura GellyRoll Moonlight Bold 10 Pens
Shuttleart Acrylic paint pens
Everything has worked beautifully and I've been able to successfully achieve nice shading and blending.
Note: All of the coloring tools I’ve mentioned above can be found and purchased right here on Amazon.
I own lots of Coco books and love coloring in them. Their illustration style is calm and friendly, making coloring in them a relaxing and enjoyable experience. There were only a few pages in this book that I would not find enjoyable to color such as the holiday themed pages. I wish they wouldn't always put holiday themed pages in non-holiday books, but they can easily be removed if you want and this book really only had a few, so still worth purchasing in my opinion.
You can tell much thought and care went into creating illustrations that would be fun to color while also helping to reduce stress, which is one of the things we all in the coloring community love about coloring right?! Coloring in Coco books is such a fantastic way to reduce stress and their designs are top notch.
A highly recommended coloring book for all ages! I hope you found this review helpful!

Love these books. Better for alcohol markers
Format: Paperback, Format: Paperback
I like these coloring books because of the designs, thw fact that the back page is empty (thinking of bleeding) and the amount of drawings on the book. Meaning, its worth for the money. These are cute.
Alcohol markers: these pages are made for this kind of markers. They blend well.
Acrylic markers: these are not the best pages for these markers. Need to re-do strokes to get good coverage. Are not porous enough. Meaning, I can see the strokes on these pages; but, in other type of paper, the acrylic markers work better with single strokes.
First picture: acrylic marker (see the strokes)
Second picture: bleeding on back of paper (alcohol marker)
Third picture: alcohol markers (other Coco Who book)
