I practice lecoloriage said adult and I have long kept this box of crayons in Wish List without buying because the price is a real heartbreaker. One evening, when my work pissed me well, I have commanded, saying that after all I deserved the stroke well all I had to manage. I do not regret them. Their layout is fluid and flexible. The brush tip allows precise but as thick traces. The colors are beautiful. What also attracted me is that you can buy the felts to the unit to complete the subsequent box. But at what price !!!!
