I'm reaching out to inquire about the density of your acrylic paints, as I'm a fan of your entire range for Acrylic FluidArt here in Portugal. I've been using them for various projects and have been impressed with their performance. However, I've noticed that there's no clear information on the packaging regarding the transparency or density of the paints, which I find quite essential for my work. Do you happen to have any charts or resources that provide details on the density and transparency levels of your products? Having this info would really help me in selecting the right colors and enhancing my artwork. Appreciate your help! Looking forward to your response.
