Returns & Refund Policy

We want you to be happy with every spool and every machine. Here is exactly what happens if something is wrong.

Damaged, defective or wrong item

• Tell us within 3 days of delivery — call, WhatsApp or email with your order number and clear photos (an unboxing video is best).
• We will arrange a replacement at no cost to you. If a replacement is not available, we refund the full amount including the delivery charge.
• Please keep the product, its box and all accessories until the case is resolved.

Changed your mind

• Filament, resin and accessories: returnable within 7 days of delivery if unopened, sealed and in original packaging. Opened filament or resin cannot be returned for hygiene and quality reasons — once a seal is broken we cannot guarantee it to another customer.
• 3D printers, laser engravers and other machines: returnable within 7 days only if the box is unopened and factory-sealed. Once a machine has been set up or used, it is covered by warranty rather than return.
• Return courier cost for change-of-mind returns is paid by the customer, and the original delivery charge is not refunded.

Warranty claims (printers & machines)

Machines carry the manufacturer's warranty from the invoice date. Costareen handles the claim in Bangladesh: contact us with your invoice and a description or video of the fault, and we will diagnose, repair or replace parts according to the manufacturer's terms. Physical damage, liquid damage, misuse, unauthorised modification and worn consumables (nozzles, build plates, belts) are not covered.

How refunds are paid

• Cash on Delivery orders are refunded by bKash or bank transfer to the account you nominate.
• Online payments are refunded to the original payment method.
• Refunds are issued within 7 working days after we receive and inspect the returned item. Your bank or wallet may take a few more days to show it.

How to start a return

1. Contact us at [email protected] or +880 1681 443070 with your order number.
2. We confirm eligibility and tell you whether to send the item by courier or bring it to our office (House 29, Road 9, Block H, Mirpur 2, Dhaka 1216).
3. Pack the item safely in its original box. We inspect it on arrival and process the replacement or refund.
