What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastic shedding or degradation
Silicone cases are not classified as microplastic sources under normal use, but extreme abrasion or weathering over many years could theoretically produce fine silicone particles. Risk is minimal for a protective case in typical indoor storage.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Marshall does not disclose printing process or ink composition for case graphics. Silicone base material itself does not contain cadmium or lead, but colored inks on surface are not independently tested in available records.
Source, FDA ↗Volatile organic compound (VOC) off-gassing
Liquid silicone does not emit formaldehyde, benzene, or other common VOCs during storage or use. No odor complaints or air quality issues have been reported for this product category.
Colorant or additive toxicity
Marshall does not disclose pigment sources or heat stability of colorants in the liquid silicone formula. Food-contact safety testing is not applicable to this product, reducing concern for color migration.
Surface contamination or bacterial growth
Silicone is inherently antimicrobial and non-porous, making bacterial colonization unlikely. Case does not retain moisture or create humid microclimates that would support mold or pathogen growth.
The full breakdown
What it's made of and why it matters
This case is constructed from liquid silicone rubber (LSR), a thermoset elastomer created by cross-linking silicone polymers. LSR is chemically inert at room temperature and does not leach plasticizers, BPA, or volatile organic compounds into contact surfaces. The material is inherently non-porous and resistant to degradation from normal use, storage, or brief temperature exposure typical of consumer electronics accessories.
The brand's record and disclosure
Marshall does not publicly disclose detailed materials sourcing or third-party safety testing results for this accessory line. No recalls or regulatory actions specific to Marshall cases have been recorded. The brand's PFAS stance is undisclosed, but liquid silicone as a base material does not require PFAS additives for water or stain resistance.
How it compares in its category
Liquid silicone cases are among the lowest-risk protective accessories available. They outperform cheaper PVC or vinyl cases (which may contain phthalates or lead stabilizers) and soft polyurethane cases (prone to off-gassing and degradation). Hard polycarbonate alternatives carry slightly higher heavy metal risk in printed logos but offer better durability; LSR cases prioritize chemical safety over impact protection.
If you buy it
Store the case in a cool, dry location away from direct sunlight to prevent minimal surface wear or color fading over years of use. No special cleaning is required; warm soapy water and air drying are sufficient. LSR does not require replacement unless visible tears develop, which rarely occur under normal storage use. Avoid prolonged contact with strong solvents or oils, though incidental exposure poses negligible risk.
