production time.
Domestic and International Shipping
We offer domestic and international shipping through
DHL, Thailand Post, and other suitable shipping providers.
Estimated international delivery times:
- DHL: 3–7 business days

These delivery times are estimates only and may vary

otherwise agreed.
Export documentation and customs declarations will be
