# MiaMily Carry On Luggage 18in \(43ltrs\) Midnight Black \| 2 sellers, live prices, prepared checkout ## Built for shopping agents: what RoboTrunk does for every product We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built. RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product. - **Deep research:** We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. `check_product` returns them with a source for each. *This product:* 39 checked facts, research depth trimmed read, checked 2026-10-05T14:48:30.052Z, in the [evidence pack](/agent/evidence/babykingdom-com-au--miamily-carry-on-luggage-18in-43ltrs-midnight-black). - **Receipts:** Every published fact has a receipt showing its source quote. `check_product` and `get_product` return the checked facts that have one. *This product:* each checked fact listed below has one; the source quotes are in the [evidence pack](/agent/evidence/babykingdom-com-au--miamily-carry-on-luggage-18in-43ltrs-midnight-black). - **Safety:** `check_product` asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. *This product:* this page holds no recall result for it yet; `check_product` asks the regulators now. - **Recall watch:** `watch_recalls` tells the buyer if a product bought here is recalled later. - **Second-hand listings:** `check_listing` runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. - **The real price:** The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on: `check_product` and `search_catalog` take the buyer's country and postcode. *This product:* this store's price was read from its catalogue at 2026-10-26T19:58:24.270Z. - **A checkout that finishes:** RoboTrunk lists only stores whose agent checkout it has verified. `create_checkout` prepares the order at the store; `complete_checkout` returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs. - **Markdown copy:** Every page has a Markdown copy: [this page's copy](https://robotrunk.com/products/ucp/babykingdom-com-au/9191575486696.md). - **Photos and ratings:** Search results carry the product photo and, where the store's own page publishes one, its rating (`search_catalog`). - **Fit answers:** `check_fit` answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known. - **Back-in-stock watches:** `watch_back_in_stock` starts a watch on a listing the store shows as sold out; `get_back_in_stock_watch` shows when it is back in stock. - **Maker's manual:** `ask_product_manual` answers from the maker's manual with the exact passage and page, or says the manual does not cover it. - **Tools and guide:** Every tool and its description is at https://robotrunk.com/mcp; the guide is at [/agents\.md](/agents.md). - **Research from other stores:** Coming soon: reading other stores' listings of the same product as new research sources.

The full evidence pack, with every citation, source and gap: [evidence pack](/agent/evidence/babykingdom-com-au--miamily-carry-on-luggage-18in-43ltrs-midnight-black) ## Questions we researched but could not confirm Every fact above is cited. To find them we read the store listing, the maker's page, the spec sheet, the manual, blogs and the recall records of CPSC \(United States\) and Health Canada and searched for regulator recall notices, owner reviews, owner forums and video reviews. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess. - Does the shell's coating chip, peel or rub off with heavy use? - Which specific airlines' overhead bins has this exact case been confirmed to fit? - What exactly does the 5\-year warranty cover, and how is a claim made? - Is there a height limit for a child riding on the seat? - Can replacement wheels, handles, locks or seat latches be bought separately? - Can the interior lining be removed and washed? - What are the interior packing dimensions? - Does the seat lock in place when folded up or down? - How much weight can the bag hook on the back hold? - Does this case carry any Australian safety certification? - Does the child seatbelt have a stated size or weight limit? - How scratch\-resistant is the Midnight Black finish in practice? To buy this through RoboTrunk, pass merchant `babykingdom-com-au`, product_id `gid://shopify/Product/9191575486696` and one variant_id from the list above.
