Refund and Returns Policy
Overview
This policy applies to LEGO Boy kits and related parts sold by Protomattic Designs. The LEGO Boy is a DIY kit that requires advanced soldering and assembly. Because the outcome depends heavily on the builder’s skill, tools, and donor parts, our return policy is limited. Please review it carefully and read the assembly documentation before purchasing or starting your build.
Return Eligibility
You may return a kit within 30 days of delivery if all of the following are true:
- The kit is unused, unmodified, and complete, in the same condition you received it.
- All components are in their original packaging, including any sealed or anti-static bags.
- You provide an order number or proof of purchase.
Modified or Assembled Items Are Not Returnable
A kit or component is no longer eligible for return or refund once any work has been performed on it. This includes, but is not limited to:
- Soldering, desoldering, reflowing, or applying heat to any board or component, by any method (iron, hot air, preheater, oven, etc.)
- Installing any part onto a kit board, including a CPU, SRAM, or any other component harvested from a donor Game Boy or another device
- Applying flux, solder paste, adhesives, or cleaning chemicals
- Cutting, drilling, sanding, painting, or otherwise altering any PCB, 3D-printed part, or other kit component
- Connecting boards to power or a battery
- Any other change that leaves an item different from how it was shipped
This applies whether the modification was done by you or by anyone else, and whether or not it was successful. If the kit has been modified, it can’t be returned. This includes cases where it doesn’t work after assembly.
Items and Materials We Are Not Responsible For
Protomattic Designs does not accept returns for, provide refunds for, or replace any of the following:
- Donor consoles and harvested parts. This includes the donor Game Boy, CPU, SRAM, or any other part you supply. We are not responsible for chips or boards that are damaged, defective, or incompatible, including damage during removal or installation.
- LEGO® set 72046 or any other LEGO product. These are purchased separately from third-party retailers. Returns are handled through the seller you purchased from.
- Cartridges, tools, batteries, or accessories not purchased from us
- Digital content, such as build instructions, PDFs, and assembly guides
Defective or Damaged Items
If a kit component arrives damaged, defective, or missing, contact us at support@protomattic.com within 60 days of delivery. Include your order number, a description of the problem, and clear photos.
- Claims must be made before the affected part has been soldered, installed, or modified, so we can confirm the issue.
- If a defect is confirmed, we will replace the affected component. If a replacement isn’t available, we will issue a refund for that component.
- Please don’t send anything back until we reply with instructions.
Minor cosmetic variations in 3D-printed parts, such as layer lines or slight color differences, are normal and not considered defects.
Pre-Orders
LEGO Boy kits sold as pre-orders have not been produced or shipped yet. Every ship date shown on a pre-order, whether on the product page, at checkout, or in an email, is an estimate and is not guaranteed. Production of custom hardware depends on PCB fabrication, component availability, testing, and supplier timelines. Some of these are outside our control and can cause delays.
Cancel anytime before shipment. You may cancel your pre-order for any reason at any time before your kit ships, and you’ll get a full refund. Email support@protomattic.com with your order number.
If the estimated ship date changes. If we expect your kit to ship later than the estimated date, we’ll email you before that date with an updated estimate. You can then either:
- Keep your pre-order and wait for the new estimated ship date, or
- Cancel for a full refund.
Your choice to keep or cancel applies to each new estimate. If the date moves again, we’ll notify you again, and you keep the same right to cancel for a full refund.
Refund timing. Pre-order cancellations are refunded in full to your original payment method, including any shipping charges paid. We process them within 7 business days of your request. It may take additional time for your bank or card issuer to post the refund.
Once your kit ships, the pre-order is complete, and the standard return terms in this policy apply.
Refunds
After we receive and inspect your return, we’ll email you to confirm it arrived and let you know whether your refund is approved.
Approved refunds go back to your original payment method within {X} business days. Original shipping charges are non-refundable.
Late or Missing Refunds
If you haven’t received your refund, first check your bank account again. Then contact your credit card company or bank, since it can take some time for a refund to post. If you still haven’t received it, contact us at support@protomattic.com.
Shipping Returns
Mail approved returns to:
Please do not send any items back without contacting us first. You’re responsible for return shipping costs unless the return is due to our error. We recommend a trackable shipping service, since we can’t guarantee we will receive items lost in transit.
If your return includes a lithium battery, contact us first. Carriers have specific rules for shipping batteries.
