Travel Jewelry Case vs Vintage 1940S Art Deco Helzberg's Jewelers Early Plastic Jewelry Case: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) from synthetic exterior and adhesives, Azo dyes in colored fabric lining and Microplastics from synthetic material degradation on the Helzberg Diamonds and not on the Helzberg Diamonds.
• We flag Formaldehyde release (phenolic resin pathway), Plastic degradation and microparticle shedding and Moisture absorption and mold growth on the Helzberg Diamonds and not on the Helzberg Diamonds.
• The Helzberg Diamonds is Fabric lining, likely polyester or cotton blend; exterior typically leather or synthetic material where the Helzberg Diamonds is Early plastic (likely cellulose acetate or phenolic resin), 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.
