马来西亚采购需求：和纸胶带、计划贴纸、牛皮便签、日记卡、翻领别针、金属书签

I'm looking to purchase multicoloured pins that are approximately 4x4 cm in size. Ideally, I would like to order around 30 pieces of these pins to start with. Could you please provide details about the available options, including colors, materials, and pricing? Additionally, information on lead times and minimum order quantities would be helpful. Thank you!
