Coco Wooden Square Takeout Bento Box
Lower concern; wood bento boxes pose minimal PFAS risk unless coated with undisclosed water/grease-repellent finish.
Wooden takeout bento boxes typically contain no PFAS-laden coatings. However, no public information confirms Naturally Chic's specific finish or any treatment applied to this product. If the interior has a glossy or water-resistant coating, request disclosure before purchase.

No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This bento box is likely made from bamboo or hardwood composite bonded with food-safe adhesives. Wood itself does not leach BPA, phthalates, or microplastics into food, unlike plastics. The primary chemical risk depends entirely on what surface treatment (if any) Naturally Chic applied: unfinished wood is inert, but opaque finishes or water-repellent coatings could introduce synthetic resins or undisclosed additives. The square design and food-contact claim suggest it is intended for direct contact with ready-to-eat foods rather than hot liquids.
The brand's record and disclosure
Naturally Chic provides no publicly available material safety data, manufacturing transparency, or third-party certifications (FSC, food-contact testing) for this product. The brand's silence on coating composition is the main disclosure gap; many wooden food containers use epoxy, polyurethane, or wax finishes without listing them. No recalls, safety violations, or documented complaints about this specific model appear in public records. Without certification from NSF, FDA clearance documentation, or manufacturer specs, you cannot confirm whether the finish is food-safe or contains low-concern additives.
How it compares in its category
Wooden bento boxes rank well against plastic alternatives (which carry BPA/phthalate risk) and ceramic boxes (which may have lead in glazes). Most branded wood bento boxes from larger manufacturers (e.g., Hakoya, Takenaka) disclose materials and certifications; Naturally Chic's lack of detail is below that standard. Uncoated or wax-finished wood boxes are chemically simpler than plastic or silicone hybrids, making them a conservative choice if coating composition can be verified.
If you buy it
Do not use in microwave or dishwasher, as heat and moisture degrade wood and can mobilize any surface finish. Hand wash with mild soap and dry immediately to prevent swelling, mold, and degradation of adhesives. Inspect the surface for cracks, splinters, or peeling after 6-12 months; replace if coating deteriorates or wood shows signs of contamination. Store in a dry place; prolonged damp storage risks fungal growth and accelerates breakdown of the box structure.
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.”
Adhesive and binder off-gassing (formaldehyde/VOCs from composite)
If this is a bamboo or hardwood composite (plywood-like construction), the glue binding the layers may contain urea-formaldehyde or polyurethane resins. Exposure risk is low for cold food storage but higher if the box is heated or left sealed for prolonged periods. No test data for this specific product is publicly available.
Surface finish composition undisclosed
Naturally Chic does not specify whether a lacquer, epoxy, polyurethane, or wax finish was applied. If present, these coatings could contain volatile organics (VOCs), low levels of residual monomers, or heavy-metal drying agents. Food contact safety cannot be confirmed without manufacturer disclosure or third-party testing.
Wood degradation and splinter/crack formation
Wooden food containers degrade over time, especially if exposed to moisture or temperature swings. Splintering poses a physical ingestion risk; splits in wood can harbor bacterial growth if not cleaned thoroughly. This is a durability issue rather than a chemical one, but affects food safety after extended use.
Microbial growth if not dried properly
Wood is porous and absorbs water. If the bento box is not dried immediately after washing or stored in humid conditions, mold and bacteria can colonize the material, especially at joints and adhesive lines. This risk is inherent to wood food contact ware and requires disciplined care.
Heavy metals in pigments (if colored stains/dyes used)
If the box has colored stains or decorative dyes applied, cadmium or lead could theoretically be present in organic pigments. No evidence of this in Naturally Chic products is on record, and natural wood color suggests minimal dye use. Confirm with the brand if dark staining is visible.
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.
