I'm in the market for a specific type of masking tape that's known for its flatback design. Could you please let me know if you have this product in stock and where I might be able to purchase it? Additionally, if you could provide any details regarding pricing, minimum order quantities, and shipping options, that would be really helpful. Looking forward to your prompt response on this! Thanks!
