I'm looking to source a variety of stationery supplies for my business. Specifically, I need A4 copy paper with weights ranging from 70 to 80 gsm, along with other standard paper types that you may offer. Could you provide details on the available options and pricing? Additionally, I'm interested in permanent markers, whiteboard markers, and pens. Any information on your product range in these categories would be appreciated. Furthermore, I would like to explore your offerings of school and office stationery items, including notebooks, folders, envelopes, and similar products. Please share your catalog or a list of items available, along with pricing and minimum order quantities. I'm eager to review these options to facilitate a potential order.
