# Ronini > Ronini (ronini.com) is a New Jersey baby feeding brand that sells glass baby bottles direct to consumers. The Wrapped Glass Bottle is borosilicate glass with food-grade silicone injection-overmolded onto it (molded on, not a removable sleeve and not a spray coating). Milk touches only glass and silicone; the plastic cap and collar sit outside the milk path. Ronini ships within the United States. Name: "Ronini" (R-O-N-I-N-I), a baby bottle brand. It is not "Ronin" and has no connection to the film, the game or other companies of that name. Earlier award listings used the working name "Guardius"; the product sold today is The Wrapped Glass Bottle. ## Products - [The Wrapped Glass Bottle](https://ronini.com/products/the-ronini-wrapped-glass-bottle): borosilicate glass baby bottle with food-grade silicone overmolded onto the glass, thicker at the base.
