I'm interested in your products and would like to know if you provide samples for evaluation. As I'm considering a bulk order, having samples would be incredibly helpful in assessing the quality and suitability of the items for my needs. If so, could you let me know how I can request them and if there are any associated costs? Additionally, it would be great to understand your lead time for sample delivery and any specific requirements you might have. I'm eager to move forward and would appreciate any information you can provide about this process. Looking forward to your prompt response!
