The delivery time of your o ring varies depending on your location and the designated shipping method. Typically, the delivery time is the time we get the order till the time goods are ready for delivery. From our perspective, in the process of raw materials preparing, manufacturing, quality checking, etc. there may be changes in the production schedule. Sometimes the delivery time may be shortened or extended. For example, when procuring the raw materials, if we have most of the required raw materials in stock, it may cost us less time to purchase the materials, which may shorten our delivery time.
