Frequently Asked QuestionsYour questions, answered.
Find detailed answers to the most common inquiries about the HKM-252947 briefcase.
What size laptop can the HKM-252947 accommodate?
The dedicated padded laptop compartment is engineered to securely hold laptops with screen sizes up to 15.6 inches (measured diagonally). The internal sleeve dimensions are approximately 15.7 x 10.6 x 1.2 inches (40 x 27 x 3 cm), providing a snug yet easily accessible fit for most standard business laptops, including popular models from Dell, HP, Lenovo, Apple MacBook Pro 16-inch (slim fit), and similar devices. We recommend measuring your laptop and comparing it against these internal dimensions to ensure compatibility.
Is the briefcase water-resistant or waterproof?
The high-density polyester fabric features inherent water-repellent properties that cause light rain and splashes to bead and roll off the surface rather than soaking through. However, the briefcase is water-resistant, not fully waterproof. It will protect your belongings during brief exposure to light precipitation or accidental spills, but it is not designed for prolonged exposure to heavy rain or submersion. For added protection in consistently wet climates, we recommend applying a fabric waterproofing spray periodically.
How does the shockproof system differ from regular padding?
Standard briefcases often rely on a single layer of thin foam that compresses fully under impact, transferring residual force to the device. The HKM-252947 employs a dual-stage absorption system: a dense EVA foam core that provides primary impact resistance, coupled with a secondary layer of high-loft polyester fiberfill that creates a graduated deceleration zone. This two-tier approach means that impact energy is dissipated more gradually, significantly reducing peak force transmission. Additionally, the base features an extra-reinforced panel to guard against the most common impact direction—vertical drops onto hard surfaces.
Can this briefcase be used as a carry-on for air travel?
Absolutely. With external dimensions of 16.5 x 12.2 x 4.3 inches (42 x 31 x 11 cm), the HKM-252947 comfortably falls within the carry-on size limits of virtually all major airlines worldwide. Its slim profile allows it to slide easily under the seat in front of you or into overhead bins. The rear luggage pass-through sleeve also enables you to secure it over the telescopic handle of a rolling suitcase, making it an excellent companion for business travel.
How should I clean and maintain the polyester exterior?
Maintenance is straightforward. For routine cleaning, wipe the exterior with a soft, damp cloth and mild soap if needed. Avoid harsh chemical cleaners, bleach, or abrasive scrubbers that could damage the fabric's finish. Allow the briefcase to air-dry naturally at room temperature—do not machine wash, machine dry, or iron. For stubborn stains, spot-clean gently with a solution of lukewarm water and a small amount of gentle detergent, then blot dry with a clean towel. The polyester material is naturally resistant to odors and staining, so with basic care it will maintain its professional appearance for years.
Does the briefcase have a warranty?
Yes. The HKM-252947 is backed by a comprehensive 24-month warranty covering manufacturing defects in materials and workmanship.
