1. Frame material
Breezm frames are made of a petrochemical material called PA12 polyamide (nylon). It is resistant to heat and has very high chemical stability. It has high strength and rigidity among plastic materials and has elasticity. Also, only safe materials that have obtained FDA and USP certification are used for making Breezm frames.

2. Temple material
- Beta Titanium: It is a titanium alloy and has better performance than pure titanium. It's strong but also has the best elasticity and resilience among metal materials. It is thin, light and bends to fit the face with its good elasticity. So, it can be designed for excellent wearability. It is allergy-free. Breezm uses Japanese materials instead of Chinese materials for high purity and safety.

3. Nose pad material (Silicon)
-Material stability: Silicon is a synthetic polymer of silicon and oxygen. It has excellent physical and chemical durability, is easy to manufacture, and is stable at high temperatures. Due to these advantages, silicone is used in various industrial fields and household goods. Silicone is known to not react with the body due to its lower chemical reactivity than other polymers, and a stable medical silicone material is used as the nose pad material in skin irritation tests.
