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)

Grab one of these for some relaxing coloring therapy!
Format: Paperback
such an adorable coloring book! I would recommend this for adults who like to color as well as children. Coloring pages are cute, easy pictures to color -nothing complicated. Everything is large enough to color easily. I look forward to sitting down with this coloring book and getting some stress-free time coloring.

Charming Coloring Book — Fun for All Ages
Format: Paperback
This coloring book has quickly become a favorite in our house! The illustrations are adorable and relaxing, making it just as enjoyable for adults as it is for kids. My daughter and I have spent hours coloring together, and it’s been a great way to unwind after school or on quiet weekend afternoons. What I love most is how versatile it feels — the designs range from simple and playful to more detailed, so everyone finds pages that match their mood and skill level. It’s also a fun way to keep little hands engaged without screens. Whether you’re looking for a creative activity to share with your kids or a gentle, artistic escape for yourself, this coloring book delivers plenty of charm and enjoyment. The only reason giving 4 stars is because of the price. Although the book is great, I do not think it is worth almost $10.
