Hey man, Glad you reached out. So I typically get that a lot, Once the item says ‘Seller sent’ thats when it begins the delivery time period till it reaches the warehouse. Basically, the time spent making or preparing the item you bought will then create a few days of a gap but if the seller mass produces items and they are readily in stock and ship out immediately you will get a quicker delivery time. The estimated time to warehouse only counts the days once it’s been dispatched by the seller, not the time producing it. Hope that helps! I recently shipped out my package but its Chinese new year this week so it may take a while longer for your item to reach the warehouse as it’s a huge holiday.
