美国采购需求：竹纤维厕纸（无塑料），优质竹纤维厕纸，可生物降解厕纸，无芯厕纸，无塑料厕纸，印花厕纸

I'm interested in evaluating the quality of your unbleached toilet paper before placing a larger order. Would it be possible for you to send me a free sample? I want to ensure that it meets the standards and specifications we require for our business needs. Additionally, it would be helpful if you could provide some details about the product, such as the materials used, the dimensions, and any certifications it might have. This information will assist me in making a more informed decision regarding a potential purchase. Thank you for considering my request!
