A4 Fireproof Bag With Combination Lock

Form factor: Tailored to accept unfolded A4 sheets (210 × 297 mm) and slim accessories — internal layout confirmed compatible with standard UK passport dimensions and common USB-A/USB-C drives. Weight class: Light enough for daily carry without fatigue; handle attachment points reinforced with stitched webbing. Material composition: Pure glass fiber laminate — non-toxic, odourless, and free from PVC, latex, or flame-retardant additives. Sealing: Two independent YKK-style zippers with double-slider mechanism and tactile feedback for confident closure. Protection logic: 12-layer build functions as a thermal capacitor — absorbing and dissipating radiant energy across strata — proven to maintain sub-175℃ internal temps for ≥30 minutes at 6400℉ surface exposure. Lock mechanism engages directly onto zipper sliders — adding mechanical obstruction beyond zipper teeth alone. Outer surface sheds water droplets visibly, confirming active moisture barrier function. Contextual usability: Equally appropriate for securing birth certificates in a nursery drawer, storing tax records in a home office, or backing up encrypted drives during international travel — its neutral aesthetic and quiet operation ensure discretion and compatibility with varied interior settings.
