C03 Leather Protective Case with Shoulder Strap For Active 7/Active 10 Pro vs Onn Waterproof Phone Pouch, Clear Compatible with iPhone, Samsung, Google, and Huawei with screens up to 7: which is safer?

Where these two actually differ

• We flag Heavy metals in leather tanning (chromium, lead), Synthetic dyes and colorants in leather and strap fabric, Volatile organic compounds (VOCs) from tanning and finishing and Formaldehyde in leather finish resins on the Blackview and not on the Sony.
• We flag Phthalate leaching (PVC only), Waterproof coating composition unknown, Microplastic shedding with wear and Degradation under UV and heat exposure on the Sony and not on the Blackview.
• The Blackview is leather (primary material), shoulder strap where the Sony is PVC or TPU with unspecified waterproof coating, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Blackview is the one to buy.
• We are less certain about the Sony grade, at 35% confidence against 72%, because it discloses less.
