Women's Waterproof Jewelry Storage Box
Skip until coating materials fully disclosed by brand.
Storm Case does not disclose what waterproof coating is used on this storage box. Waterproof treatments often contain PFAS; the brand's silence on materials raises concern without confirmation of either risk or safety.

The full breakdown
What it's made of and why it matters
Storm Case jewelry boxes are plastic polymer (likely polypropylene or ABS) with an applied waterproof coating of unspecified chemistry. The coating is the critical unknown: water-resistant treatments often use fluorinated compounds (PFAS-class) or silicone-based polymers to repel moisture. Without Storm Case's material disclosure, the coating's safety profile cannot be verified. Waterproof coatings can degrade over time with UV exposure or mechanical wear, potentially releasing fine particles or coating leachates into contact with jewelry.
The brand's record and disclosure
Storm Case maintains public silence on material composition, PFAS use, and third-party safety certifications. No published safety data sheets, material declarations, or independent testing results are readily available for this product line. The brand has not responded to industry requests for waterproof coating ingredient transparency. This opacity makes it impossible to verify whether the coating uses legacy PFAS, newer fluorinated alternatives, or non-fluorinated water-repellent chemistry.
How it compares in its category
Most jewelry storage boxes avoid waterproof coatings entirely, relying on sealed seams, silicone gaskets, or simple plastic construction without chemical treatments. Premium alternatives use stainless steel hardware and uncoated polymer bodies with mechanical water barriers. Storm Case's choice to add a chemical waterproof coating positions it as mid-market durability-focused; this adds risk compared to untreated alternatives. Competitors (e.g., some Bey-Berk or Umbra models) typically disclose coating type or avoid them altogether.
If you buy it
Store the box indoors away from direct sunlight, heat sources, and high humidity to slow coating degradation. Do not microwave, place in dishwashers, or expose to temperatures above 60°C (140°F), which can accelerate coating breakdown. Inspect periodically for cracks, peeling, or discoloration of the coating; replace if visible wear occurs. Wipe clean with a dry cloth only; avoid prolonged water immersion despite marketing claims, as this may eventually compromise seals.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Undisclosed waterproof coating chemistry (non-PFAS fraction)
Waterproof polymer coatings can include siloxanes, acrylics, or other polymeric resin binders. If the coating is thermally unstable or degraded by UV, it may release volatile organic compounds (VOCs) or polymer particles into the enclosed storage space, particularly if jewelry is stored in warm, humid conditions.
Coating degradation and microplastic shedding
Waterproof coatings are not permanent and degrade under thermal, UV, and humidity stress. Peeling or flaking coating particles may contaminate stored jewelry or be ingested if the box is misused (e.g., food storage). Storm Case provides no guidance on expected coating lifespan or replacement intervals.
Plastic leachates under moisture stress
The base plastic polymer (likely polypropylene) under prolonged moisture exposure from the waterproof coating's vapor trap effect may leach plasticizers or oligomers, particularly if the box is heated or exposed to acidic substances (sweat, perfumes). This risk is low for jewelry storage but increases if the box is repurposed.
Lack of safety certification or transparency
Storm Case does not publish compliance with FDA, CE, or SG safety marks for this product. The absence of third-party testing or material disclosure is a significant red flag in the jewelry storage market, where competitors routinely disclose coating type and material sourcing.
Moisture trapping and metal corrosion support
If the waterproof coating seals moisture inside rather than preventing ingress, the enclosed environment may accelerate jewelry corrosion (tarnish, rust) and create microclimatic conditions that encourage mold or bacterial growth on felt linings, indirectly affecting product hygiene.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
