I'm looking to purchase 4 pro glasses that meet specific technical standards for an upcoming project. It's crucial that these glasses not only provide excellent optical clarity but also adhere to safety regulations. Could you please confirm if you have these in stock? If possible, share details on the available options, including materials used, any certifications, and pricing. Additionally, I'd like to know about the lead time for delivery, as timing is essential for this order. If there are any bulk discounts or promotional offers, please include that info as well. I'm excited to hear back from you soon, so we can move forward with this order!
