Marstoy Promo Code & Coupons — 5% Off — October 2026

Marstoy carries a broad mix of building-block products, including technical vehicles, architecture, spacecraft, military-themed models, MOCs, decorative builds, brick kits, individual parts, and minifigures. Because the store works with multiple manufacturers, the selection is much wider than a typical single-brand catalog.

No. Marstoy operates mainly as a retailer and sourcing platform that carries products from different building-block manufacturers. This means brick feel, packaging, instructions, and overall build experience can vary from one set to another, so it is worth checking the individual product page before ordering.

Piece count is a useful starting point, but it does not tell the whole story. A smaller technical or MOC build can sometimes be more complicated than a larger display model. Look at the design, mechanisms, number of small details, and available product information when deciding whether a set suits you.

Marstoy offers worldwide shipping to many countries and regions. Available methods and costs depend on the destination and order, and some locations may also be subject to customs duties or local taxes. If your country or region does not appear during checkout, Marstoy recommends contacting its support team.

Delivery time varies by destination, shipping method, customs processing, and product availability. Marstoy may also wait until every item in an order is ready before dispatching the package, so orders containing products that take longer to source can have a longer preparation period.

Temporary gaps in tracking can happen while an international shipment is moving between logistics networks or clearing customs. Marstoy notes that sea or rail shipments may not show further tracking activity until they reach the destination country or port, so a period without updates does not necessarily mean the parcel has stopped moving.

Changes and cancellations need to be requested quickly. Marstoy generally allows them only before the order has entered the relevant domestic shipping stage, and its refund policy states that cancellation requests must be made within the first 24 hours and before shipment. Contact customer support as soon as possible if you notice an incorrect product, quantity, or address.

Eligible purchases can generally be returned within 30 days of purchase. Products must be unused and kept in their original condition with the original packaging. Shipping and handling costs are normally excluded from the refund unless Marstoy caused the issue, and sale or clearance items are listed as non-returnable.

Yes. Marstoy offers a service called Project D for builders who already have a parts list for a custom project. Customers can provide their required pieces in an Excel file, and Marstoy can source the bricks for the build. Pricing can vary when unusual or specialized pieces are required, and shipping is separate.

Marstoy currently supports online payment through PayPal, including payment with a PayPal account and credit-card payment through the PayPal checkout system. Because available payment options can change by country or checkout configuration, the checkout page is the best place to confirm what is available for a specific order.
