Hello ❤️ First of all, thank you very much ☺️ Our fabrics are of the highest quality, but as a textile manufacturer, I must say that there may be a slight lightening in the color of black fabrics. � � We do not recommend putting it in the machine because it contains hard holding material, its structure may deteriorate. You can wipe it from the outside with a wet cloth or it can be hand washed. � � However, we also have customers who wash it in the machine and use it. This choice is yours, but we wanted to warn you beforehand. � � By the way, good luck with your exam. I hope you get where you want to be, with love. � �
