C03 Leather Protective Case with Shoulder Strap For Active 7/Active 10 Pro vs Waterproof Phone Pouch Full Cover Case for All Models: 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 Ozark Trail.
• We flag Undisclosed waterproof coating (likely fluorocarbon-based), PVC off-gassing and plasticizer leaching, Microplastic shedding from coating and Mold or bacterial growth in storage on the Ozark Trail and not on the Blackview.
• The Blackview is leather (primary material), shoulder strap where the Ozark Trail is Neoprene or PVC 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 Ozark Trail grade, at 35% confidence against 72%, because it discloses less.
