I'm interested in your fully automatic racket stringing machine for both badminton and tennis. Could you provide the current pricing details, any variants or optional accessories that might affect the cost, and the warranty terms? Additionally, do you ship to Tehran, Iran? Please share the available shipping methods, costs, and any customs documentation support. Also, are there local repair services or authorized partners, and can I get spare parts locally, or will they need to be ordered directly from you? Looking forward to your response!
