Delivery is part of the plan.
Protected parcel, box-crate or freight options are assessed for the completed model. Tall, fragile or oversized sections may travel separately with reconnection instructions.
Before purchase: we agree the assembled dimensions, destination, packing, transport charges and any final reconnection or setup. Shipping, crating, taxes and itemized import charges are additional unless expressly included.
Before dispatch: your commission includes finished-model photographs and a final visual inspection. No particular carrier, one-piece shipment or on-site installation is promised unless included in your quote.
Supplier reference · November 8, 2026
Supply confirmed personally.
Manufacturer US retail page offers Add to Bag. Appropriate business sourcing must be confirmed.
Supplier stock is not finished BINGSERV inventory. We verify the complete kit, instructions, replacement support and an appropriate supply route before accepting payment. Customer-owned kits are welcome for an assembly-only quote.
Assembly planning
4–6 weeks
A preliminary assembly estimate, not a delivery promise. Your written quote confirms procurement, our agreed start, completion and shipment timing before payment.
Your assembly scope, included features and available build capacity are agreed before acceptance.
Details that matter
Your exact version.
Only set 71837 and its included components are covered. Other NINJAGO City sets are separate projects.

Before your commission
Exceptional models. Clear expectations.
What does the displayed price include?
The identified kit in the agreed configuration and standard assembly, parts sorting, progress updates, finished-model photographs and a final visual inspection. Included electronics or mechanisms are checked to the agreed scope. A planning budget is not a firm quote. Prices are BINGSERV cost-based asking prices, not claims of collectible resale value.
What is quoted separately?
Protective packing or crating, shipping or freight, applicable taxes, itemized import costs, display cases, optional lighting, upgraded stands, custom painting or weathering and on-site setup are additional unless expressly included. Your written quote identifies the complete scope and charges before payment.
Can large models be shipped?
We consider protected parcel shipping, box-crating, custom crates and palletized freight according to the model and destination. Size, fragility, weight, insurance availability, delivery access and any final reconnection are reviewed before acceptance. Delicate sections may travel separately. One-piece delivery, a particular carrier or on-site installation is included only when specified in the quote.
What happens after an inquiry?
We contact you to confirm supply, the exact model and finish, assembly capacity, the complete quote, payment arrangements and the delivery plan. You approve the written terms before payment. Submitting this form does not create an order, reserve inventory or enroll you in marketing.
What happens if a project cannot be fulfilled?
We may decline an inquiry we cannot responsibly source, assemble or transport. If BINGSERV must cancel an accepted, unshipped order because it cannot be fulfilled, payments for that cancelled order are promptly refunded. No alternative model, finish or price is substituted without your approval. Customer-requested changes or cancellation are handled under the written terms and applicable consumer rights.
When will my model arrive?
Page timings are preliminary assembly estimates, not guaranteed delivery dates. Your written quote establishes the sourcing, assembly and shipment schedule before payment. If the agreed shipment timing cannot be met, we contact you with the available delay or cancellation/refund options; a delay is not silently treated as your agreement.
Are models or complete kits held in stock?
The catalog offers made-to-order commissions, not a warehouse of completed models. Supplier references are dated snapshots, not live inventory. Complete-kit availability and sourcing are confirmed before acceptance. Some full-payment kits arrive in installments; we do not treat them as immediately complete. Sold-out and preorder editions remain sourcing inquiries until a suitable kit is secured.
What do the pictures represent?
Exact-kit product photographs are supplier/manufacturer references, not proof of a completed BINGSERV commission. The restored promotional artwork is labeled separately and may show illustrative lighting, scenery or display furniture. The actual kit reference, product photographs and written quote define what you receive. Painted samples, manufacturer previews and optional accessories are identified where relevant.
Is BINGSERV affiliated with the brands?
BINGSERV is an independent assembly and fulfillment service, not an endorsed or authorized assembly partner of the manufacturers or entertainment-property owners. Brand and model names identify the kits. LEGO-branded listings identify genuine LEGO sets; third-party compatible-brick and mini-block kits are labeled separately. A custom model built from genuine LEGO parts is not automatically an official LEGO set.
Can you assemble a kit I already own?
Yes, you can request an assembly-only quote. We review the kit, instructions, part condition, completeness and requested finish before accepting it. Large metal, wooden, painted or electrically complex projects need an individually agreed build and handling plan. These are collector/display projects; keep small parts, magnets, delicate mechanisms and heavy components away from children and pets.
