La Bella 700T Tenor Guitar Strings
Lower concern, traditional guitar strings with no known PFAS use or treatment.
La Bella 700T tenor guitar strings are metal-wound strings (nickel-plated steel) with no disclosed treatments, coatings, or manufacturing processes known to use PFAS. Guitar strings do not typically require water-repellent coating, stain resistance, or non-stick treatments that would trigger PFAS use.

The full breakdown
What it's made of and why it matters
La Bella 700T strings are wound with nickel-plated steel, a standard material for acoustic guitar strings that has been in use for decades. The nickel plating provides corrosion resistance and tonal brightness, while the steel core offers durability under string tension (typically 150-200 pounds total). Nickel plating thickness on quality strings is thin enough (a few micrometers) that leaching into skin or saliva is not a documented concern, and the strings are not heated or ingested during normal play.
The brand's record and disclosure
La Bella is a long-established string manufacturer with no known product safety recalls or hazard disclosures on public record. The company does not publish detailed material certifications or toxicity testing data on their website, which is typical for the guitar string category but limits independent verification of contaminants. No documented controversies regarding heavy metals, coatings, or manufacturing practices have been published by consumer safety organizations or third-party testing bodies.
How it compares in its category
Nickel-plated steel is the industry standard for acoustic guitar strings; La Bella 700T sits in the mainstream middle of the market, neither premium-handcrafted nor budget economy. Alternatives include phosphor bronze wound strings (warmer tone, slower corrosion) and pure nickel (brighter, less durable), but all three classes carry similar material-safety profiles. No category-wide toxicity pattern has been identified for modern guitar strings from reputable makers.
If you buy it
Strings should be replaced every 1-3 months depending on playing frequency, humidity, and sound preference; worn or rusty strings pose no acute toxicity risk but degrade in tone and may break during play. Wash hands after playing to remove dirt and sweat buildup on the strings, which reduces corrosion and extends life. Store in a dry environment; high humidity can accelerate nickel plating degradation and rust formation. No special precautions are needed for skin contact or storage around food or water.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Nickel skin sensitization (contact dermatitis)
Nickel is a known contact allergen; individuals with nickel sensitivity may experience irritation on fingertips or fretting hand with prolonged or repeated contact. This is a pre-existing condition in roughly 10-15% of the population and is well-documented in guitar players, but not specific to La Bella products.
Nickel leaching into oral cavity
No documented cases of nickel poisoning or bioaccumulation from guitar string contact with mouth or lips have been reported. The nickel plating is mechanically bonded and not soluble in saliva under normal conditions.
Steel core oxidation and rust particles
Corrosion of the steel core (visible as orange-brown discoloration) can occur in humid environments; ingestion of rust particles is unlikely during normal play but could occur if strings are excessively worn or broken. This is a degradation hazard rather than a manufacturing defect.
Zinc or cadmium in plating process residue
Modern nickel-plating for instrument strings typically uses electrolytic nickel without cadmium, and no public test data or recalls have linked La Bella strings to heavy metal contamination. Historical plating practices (pre-1980s) sometimes used cadmium as a brightener, but this is not current industry practice.
Coating degradation from sweat and humidity
Nickel plating can degrade over weeks to months with heavy playing and high humidity, exposing the underlying steel and potentially increasing nickel surface contact. This is normal wear, not a defect, and is addressed by regular string replacement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
