For all the orders ship to US from 23-Apr, the transaction cost (additional tariff and processing fees) may rise significantly. This is mainly due to the end of the de minimis trade exemption policy for small import items valued at less than $800 from China which will probably start on May 2nd. I am unable to estimate how much the transaction cost will rise at this stage. I will update you the possible solution after May 2nd when everything is clear.
I have to pause all shipments for orders to US at least until May 2nd.
I am still offering free shipping worldwide except to US.
