Review on 🌈 10-Piece Scratch Painting Rainbow Sketch DIY Kit - Night View Art Craft with Tools, A4 Paper, 2 Wooden Pens, Red & Black Scratch Pen, Small Brush - Creative Gift for Kids - Scratchboards by Jennifer Roberts

I loved this product so much I bought it twice. However, I'm just a little confused on how to use it. Most of the scratch images only have color under black and then I designed them to erase. But in these drawings I have very little gray. After just scratching the grey, I got the feeling that the painting looked half finished. So I scratched a bit more and found that the real image is under the black hole. After actually scraping the whole image off, the finished effect looked pretty sloppy. That just confused me should the scratch only show a small part of the photo or should you erase the whole thing? At the same time I like how the image looks under black and how the fireworks rub off is amazing. Some scratch images have gray patterns that are almost impossible to erase and details that have been applied with gray. If anyone else has used this product and has it indoors I would love to hear about it.
