C03 Leather Protective Case with Shoulder Strap For Active 7/Active 10 Pro vs Body Glove Tidal Waterproof Case for Galaxy S25 Ultra: 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 Samsung.
• We flag Undisclosed waterproofing chemicals (presumed PFAS-based), TPU degradation and leaching, Microplastic shedding from case wear and Seal integrity failure and moisture ingress on the Samsung and not on the Blackview.
• The Blackview is leather (primary material), shoulder strap where the Samsung is Thermoplastic polyurethane (TPU) with waterproof treatment, 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 Samsung grade, at 45% confidence against 72%, because it discloses less.
