Ethiopia Flag Distressed Waterproof Case for Galaxy S24 Plus
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPU or synthetic polymer, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
TPU plasticizer migration
TPU contains plasticizers that can leach in minute amounts under heat, sweat, or prolonged contact with skin oils. At normal use temperatures and durations, migration is negligible and poses no established health risk, but this remains a theoretical pathway for polymer degradation products.
Seal or adhesive off-gassing
Seams and adhesives used to bond TPU layers may emit trace volatile organics during the first days or weeks of use. This is normal and typically resolves within a short period; it is not a safety concern but may produce a mild odor.
Microplastic shedding from wear
TPU cases can shed microparticles over time as the material wears or flexes repeatedly. Shed particles are not ingested in normal phone case use but may contribute to environmental microplastic accumulation if disposed improperly.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
The distressed flag print may use organic or inorganic dyes. No information is available on dye composition for this specific product. Standard TPU dyes used in phone cases do not typically contain lead or cadmium, but the brand provides no material safety data sheet or dye certification.
Source, FDA ↗No established hazardous coating or treatment
The product description does not indicate application of water-repellent Teflon-family coating coatings, antimicrobial treatments, or other applied surface treatments that might introduce hazardous chemicals. Waterproofing is material-based, not treatment-based.
The full breakdown
What it's made of and why it matters
This case is constructed from TPU (thermoplastic polyurethane), a flexible synthetic polymer widely used in phone protection because it absorbs impact and resists water intrusion without requiring hazardous surface treatments. TPU does not off-gas formaldehyde or volatile organics at typical room and body temperatures, and it does not leach BPA or phthalates under normal use. The waterproofing derives from the material's inherent water resistance and sealed seams, not from applied coatings that might contain harmful chemicals.
The brand's record and disclosure
Etuui is a minor accessory brand with limited public disclosure on materials, manufacturing practices, or third-party testing. No established certifications (such as OEKO-TEX or ISO 14001) are on record for this product line. No product recalls or safety controversies involving Etuui cases are documented in public databases. The brand's silence on PFAS is typical for smaller electronics accessory makers but represents a missed transparency opportunity.
How it compares in its category
Waterproof phone cases in this price segment typically rely on TPU, silicone, or TPE materials rather than rigid plastics with epoxy coatings, making chemical hazard profiles generally low. Etuui's approach is standard for the category. Competitors like Spigen and OtterBox publish more detailed materials information and certifications; this product offers less third-party reassurance but also no identified risk markers that would elevate concern above peers.
If you buy it
Avoid prolonged exposure to direct sunlight or heat above 60 degrees Celsius, as TPU can degrade or soften. Clean the case with mild soap and water; do not use solvents or harsh detergents that could degrade seals. Inspect seals and edges annually for cracks or separation, as waterproofing depends on structural integrity. Replace if visible damage occurs or if the case becomes brittle or sticky, which signals polymer degradation.
