Flaxstic Compostable Phone Case vs Cell Phone Accessories for sale: which is safer?

Where these two actually differ

• We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the RhinoShield.
• We flag Polycarbonate degradation and monomer leaching, TPU thermal instability, Unknown thermoplastic identity and additives and Water-repellent or antimicrobial coatings (undisclosed) on the RhinoShield and not on the Pela.
• The Pela is Flax fiber and plant-based resin blend, compostable where the RhinoShield is Polycarbonate, TPU, silicone, thermoplastic (unspecified), which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Pela is the one to buy.
• We are less certain about the RhinoShield grade, at 25% confidence against 92%, because it discloses less.
