x LoveShackFancy Waterproof Floating Phone Pouch vs A610 Universal Waterproof Float Case: which is safer?

Where these two actually differ

• We flag Polyurethane degradation and plasticizer migration, Microplastics from fabric shedding or foam breakdown, Adhesive or solvent residues from manufacturing and Zipper or fastener corrosion or failure on the Case-Mate and not on the Spigen.
• We flag TPE material degradation, Microplastic shedding and PFAS in waterproofing coatings on the Spigen and not on the Case-Mate.
• The Case-Mate is Polyurethane or synthetic fabric where the Spigen is TPE (thermoplastic elastomer) with waterproof sealing, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
