The Steel Boxes set of 3 combines durable stainless steel construction with silicone lids for a secure, waterproof seal. Available in three sizes — 50 ml, 110 ml, and 220 ml — the set accommodates a range of storage needs. Each box is free from phthalates, BPA, BPS, and lead, and is certified safe for food contact. The dishwasher-safe design simplifies cleaning, though the boxes are not suitable for microwave use.
