克罗地亚采购需求：丙烯颜料、织物颜料、冷笔、颜料套装、马克笔、马克笔

I'm reaching out to inquire about the availability of fine tip liquid chalk markers in black. I noticed that your current offerings mainly include these markers in sets, but I'm specifically interested in the option to purchase them separately. Could you let me know if it's possible to order additional black markers outside of those bundled in sets? I'm looking to buy a larger quantity for my needs, so any information regarding single unit availability and pricing would be greatly appreciated. Thanks for your assistance!
