I'm looking to source high-quality black duct tape for our upcoming projects. Specifically, I need a reliable product that offers strong adhesion and durability to handle various applications. Can you provide details about availability, pricing, and any bulk purchase discounts you may offer? Additionally, I'd appreciate information on the specifications, including width and length options. If you have samples available, it'd be great to evaluate the tape before placing a larger order. Looking forward to your prompt response!
