Replacement for repair - 1 piece Square belt for repairing the opening and closing rubber of optical drive trays such as CD/DVD drives. Folded length (length when folded in half) approximately 40mm, width 1mm, inner diameter approximately 26mm. We plan to ship the item the next day via standard mail. It usually takes about 3 to 6 business days, excluding weekends and holidays. The post office seems to be operating with reduced service for standard mail, and it may take some time for delivery, but I have no experience of non-arrival. If you are in a hurry, please purchase with plenty of time.
