As a K-4 art teacher, I swear by Prang Watercolor sets!!!! The color is so much richer & truer than a lot of other "kids" watercolor sets out there. I won't name names, but there is a well known brand out there that offers one of the poorest quality watercolor sets I've come across(which is totally unlike this company!!!). Air pockets in the color cake, faded/light colors, and not enough product for the money! YOU WON'T FIND THAT WITH PRANG!!!!! I also love how easy it is to pop empty colors out & replace them with refills(make sure you order lots of blue & green!!!). The cases also seem to take a lickin' & keep on tickin'!! I've been using some of the same cases for over 7 yrs now!!!! Gotta love that. You just need to wash them up at the end of the school year & they're ready for another round(I usually pull the color tray out of the box & soak the boxes in a sink of warm soapy water). So, buy Prang Watercolor for your classroom(or your kiddo's at home)...you will not be disappointed!
