Wise Small Utility Dry Box
Dry box likely water-resistant; PFAS status undisclosed by brand.
Wise Small Utility Dry Box is a storage container with waterproof properties typical of consumer dry boxes, but the brand makes no PFAS disclosures. Waterproofing treatments sometimes contain PFAS; direct contact with brand recommended for confirmation.

The full breakdown
What it's made of and why it matters
The Wise Small Utility Dry Box is a rigid plastic storage container, most likely polycarbonate or high-density polyethylene (HDPE), designed with waterproof sealing. The water resistance likely comes from either PFAS-based coatings (common in water-resistant gear) or proprietary polymer additives; Wise has not publicly disclosed which. Rigid plastics like polycarbonate and HDPE are chemically stable at room temperature but can degrade or leach additives if exposed to sustained heat, UV, or abrasive chemicals.
The brand's record and disclosure
Wise is a consumer outdoor/storage brand without published safety certifications (BPA-free claims, third-party testing, or PFAS transparency statements) on this product line. No major recalls or safety controversies on record for Wise dry boxes. The brand's silence on PFAS status is typical for this product category, where waterproofing chemistry is often proprietary and undisclosed to end users.
How it compares in its category
Most rigid plastic dry boxes use similar polycarbonate or HDPE construction with waterproof treatments; this is a standard mid-market option. Brands like Pelican and OtterBox publish more detailed material specs and certifications. Wise occupies the price-conscious segment where transparency is lower but material durability is generally adequate for non-food storage.
If you buy it
Store only non-food items (tools, electronics, camping gear) to avoid food-contact leaching risks. Keep away from direct sunlight, heat sources above 50C/120F, and strong solvents that can degrade the plastic matrix. Inspect the seals annually and replace if cracked or discolored. Do not microwave or boil items inside; do not fill with hot liquids.
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.”
BPA or other bisphenol analogues in polycarbonate
If this box is polycarbonate (common for rigid dry boxes), it may contain residual BPA or BPS unless explicitly labeled BPA-free. Wise has not stated either way. Risk is minimal for non-food storage but increases if hot items or fatty foods contact the interior.
Plastic degradation and microplastics when heated or UV-exposed
Polycarbonate and HDPE can photo-degrade and off-gas small plastic particles under prolonged sunlight or heat. Outdoor storage in direct sun over months may accelerate this; the closed design reduces airborne release but particles can contaminate contents if stored items are later consumed.
Waterproofing additive leaching (non-PFAS unknown)
The waterproof treatment's composition is undisclosed. If it uses non-PFAS water repellents (silicones, waxes, or proprietary polymers), migration into stored items is unlikely at room temperature but cannot be ruled out without material data.
Seal degradation and bacterial/mold growth if moisture trapped
User reports and product reviews note that if seals fail or moisture is trapped inside, mold and mildew can grow in the enclosed space. Regular inspection and drying before storage prevent this; does not reflect a manufacturing defect but standard maintenance for airtight boxes.
Lead or cadmium in colorants or additives
No recalls or testing data for Wise dry boxes specify heavy metal contaminants. Standard injection-molded plastics in this category rarely use lead or cadmium pigments, but third-party testing is absent for confirmation.
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.
