I'm interested in purchasing vests designed for seniors, specifically those equipped with airbags for added safety. Could you please provide me with the pricing for a single unit? Additionally, I would like to know if you offer any bulk purchasing discounts or deals for larger orders, as that might influence my decision. It would also be helpful to get information on the available colors and sizes, as well as any customization options you offer for these vests. Please let me know about the lead time for production and shipping as well. Thanks!
