Announcement

Dear Customers, We regret to inform our valued customers that due to newly imposed tariffs by the United States on our country, the cost of shipping goods to the U.S. has increased significantly. As a small business, we’ve done our best to absorb these rising costs, but unfortunately, it has reached a point where we can no longer avoid adjusting our prices. A price increase for U.S. orders is likely in the near future (date to be determined). If you’ve been thinking about placing an order, we kindly suggest doing so before the adjustment takes effect. We truly appreciate your understanding and support — this is not a decision we make lightly, and we’re just as frustrated by the situation. Thank you for being with us.
