K&S 3937 Round Brass Tube: 4.5mm OD x 0.225mm Wall x 1 Meter Long (4 Pieces): Scale, Subject & Display Guide
The product behind this guide is K&S 3937 Round Brass Tube: 4.5mm OD x 0.225mm Wall x 1 Meter Long (4 Pieces). Because similar hobby metal tubing products can share brand names or photographs, the analysis below keeps the K&S Precision Metals title, SKU and live image set tied together as one record.
The record that separates this item
- Exact product: K&S 3937 Round Brass Tube: 4.5mm OD x 0.225mm Wall x 1 Meter Long (4 Pieces)
- Brand or vendor: K&S Precision Metals
- Product type: Hobby Metal Tubing
- SKU or catalog key: K+S3937
- Quantity wording: 4 Pieces
- Variants reviewed: 1
- Product images indexed: 1
The recorded price at verification was $22.79 before shipping and tax. At least one variant was orderable when the record was checked.
The quantity wording 4 Pieces should be reconciled with the package photo and option selected. The working catalog key is K+S3937. That key should travel with the saved URL and product image so a later comparison does not collapse this item into another hobby metal tubing listing.
Reading the source record carefully
The product page identifies the item this way: “K&S Precision Metals 3937 round brass tubing is supplied as a pack of 4 pieces, each 1 meter long. Each tube has a 4.5 mm outside diameter and 0.225 mm wall thickness. Material: brass. Shape: round hollow tube. Outside diameter: 4.5 mm. Wall thickness: 0.225 mm. Length: 1 meter per piece. Quantity: 4 tubes. Use for model building, fabrication and craft projects requiring these dimensions. Cut and finish as needed for your project. Tools are sold separately.” That excerpt anchors the guide, while the gallery, SKU and selected variant provide the remaining evidence needed for an exact match.
Practical use and compatibility
For a diecast or scale collectible, the subject name alone is insufficient. Compare body casting, finish, graphics, wheel design, interior, base markings and packaging format. On K&S 3937 Round Brass Tube: 4.5mm OD x 0.225mm Wall x 1 Meter Long (4 Pieces), the exact photo set and SKU K+S3937 are the reference pair; a model with the same vehicle name but a different wheel, road number or package is a different release.
Condition language must also match the format. A loose item is judged from the photographed surfaces and axles, while a packaged item adds card, blister, box and seal condition. A finished custom should be assessed for workmanship and disclosed modifications; a build kit should be assessed for included parts and fitment rather than as a completed collectible.
Using the item with confidence
A good collection note records what is visible and avoids unsupported rarity claims. Write down the exact color wording, graphics, wheel treatment, package condition and any disclosed customization. Market value can change; the product identity should remain reproducible from the record.
Upon arrival, compare the item with the listing images before opening or altering it. Any material discrepancy is easier to document while the original packaging and shipping materials remain intact.
What to inspect in the product images
1 product image were available to the catalog at verification. Use them as item-level evidence: zoom in on the SKU, graphics, edges, connectors, part arrangement or package callouts relevant to this hobby metal tubing. Do not substitute a generic manufacturer image when the exact listing supplies a more specific view.

The collection record worth keeping
Catalog the item under the complete title and K+S3937, then add the date received and the condition actually observed. For a project item, note where it was installed or how it was used. For a collectible, note package and display condition separately.
Retaining the exact identifiers protects the record when product titles or availability later change.
Gift considerations
As a gift, K&S 3937 Round Brass Tube: 4.5mm OD x 0.225mm Wall x 1 Meter Long (4 Pieces) is strongest when the recipient already uses this scale, format, subject or product family. Check for duplicates and fit-sensitive details before choosing it solely from the brand name.
