Anchor · Insulated Drink Tumblers
Engraved Insulated Tumbler with Anchor, Navy
Stainless steel tumbler with no coating on record.
Insulated tumblers are generally lower PFAS risk since they hold beverages without specialized coatings. Anchor's product lacks PFAS disclosure but contains no flagged high-risk components.

What Engraved Insulated Tumbler with Anchor is made of, ingredients and materials
This tumbler is constructed from stainless steel, a non-leaching metal alloy resistant to corrosion and chemical migration into beverages. The insulation layer is unspecified in product details, but commercial insulated drinkware typically uses either vacuum insulation or foam/gel layers. Stainless steel itself does not off-gas volatile compounds or degrade into microplastics under normal use, making it chemically stable across hot and cold beverages.
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.
Insulation layer composition (unspecified)
Product does not disclose whether insulation uses vacuum, closed-cell foam, or gel material. If foam-based, potential for low-level off-gassing exists over product lifetime, though risk is minimal in practice for drinkware.
Stainless steel nickel content
All stainless steel contains nickel (typically 8-12%). While leaching into beverages is minimal for food-grade stainless, individuals with severe nickel sensitivity may experience contact dermatitis from prolonged grip contact, not ingestion.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Interior seam corrosion or separation
No recalls or documented failures for this brand's tumblers. Poor seal maintenance could theoretically allow liquid ingress into insulation layers, but this is a mechanical failure, not chemical hazard.
Coating or ink migration from engraving
Engraving removes material rather than applying coating, so no ink or epoxy-based hazard is introduced. No safety data suggests Anchor uses leaching inks in their engraving process.
Microplastic shedding from insulation
Stainless steel exterior does not shed microplastics. If insulation is foam-based, mechanical degradation over years could theoretically release particles, but this would not affect beverage contact if seal remains intact.
The full breakdown
The brand's record and disclosure
Anchor is a private label brand with minimal public safety disclosure history. No documented product recalls, safety violations, or material certifications are on record for this brand's drinkware line. The brand maintains no published stance on PFAS use in insulation or manufacturing, which is typical for smaller drinkware suppliers but limits transparency. Absence of controversy does not equal verification of safety; it reflects a lack of public scrutiny.
How it compares in its category
Stainless steel insulated tumblers have lower concern for leaching hazards compared to ceramic-glazed or aluminum alternatives. This product uses materials with lower concern in the insulated drinkware category; comparable brands (Yeti, Hydro Flask, RTIC) maintain similar material profiles. The engraved design poses no additional chemical risk, as engraving does not involve coating or resin application.
If you buy it
Hand wash recommended to preserve the insulation seal and engravings; dishwasher cycling may degrade foam-based insulation over years. Avoid prolonged exposure to extreme temperature swings (boiling water followed immediately by freezing) as this can stress interior seals. Replace if the seal degrades, evidenced by loss of insulation performance or visible corrosion on seams. No special maintenance required; stainless steel is durable and does not require seasonal replacement.
