Beautiful results provided to meet the requirements. All materials are not tinted, only cotton, linen, silk and viscose can be tinted. Synthetic fabrics, labels, sewing son etc. can not take the dye. The final color depends on the base color. If the garment is stained, the stains are still visible. If you want a true color to that of the box, it is better to discolor the fabric with bleach before dyeing. So take the time to read the manual before use. With this box, I refreshed two brown pants that are now as good as new, nice money saving. I spent time writing this review to you. If you enjoy and that this has been helpful, thank you to let me know by checking YES below.
