Electropolished stainless interior

An electropolished model has a smooth stainless inner surface. A ceramic-lined model adds a ceramic finish over that inner wall. Both are options in our range, and a sample can help you choose the finish that suits your brand.

An electropolished interior is a bare SUS 304/316 stainless steel liner microscopically smoothed to reduce metallic aftertaste and mineral adhesion, whereas a ceramic-coated bottle adds a food-contact safe silica-based layer over stainless steel so coffee, tea and acidic drinks do not touch bare metal. Both options are available from MOQ 500 pcs.
