MerryTune currently ships from South Korea to the destinations available at checkout. Estimated delivery after dispatch is generally 2–4 business days for Japan, 4–7 business days for Singapore and Taiwan, 6–12 business days for the United States, and 3–5 business days for Australia.

International orders may be subject to import duties, taxes, customs-clearance fees, or local handling charges imposed by the destination country. Unless expressly stated otherwise at checkout, these charges are not included in the product price or shipping fee and are the responsibility of the recipient.

You may request a return within 30 days after receiving your item.

MerryTune products are designed, developed, and manufactured in South Korea. Production, materials, and quality-control requirements are managed according to the characteristics and intended use of each product.

We recommend machine washing on a gentle cold-water cycle using a laundry net and mild baby detergent. Do not bleach or tumble dry on high heat, as high temperatures may affect technical fabric elasticity and structural components. Detailed washing instructions are included on each product tag.
