These diffuser bottles are crafted from thick food-grade lead-free transparent glass. The bottle body features delicate diamond vertical embossed cutting, which refracts soft light to create a high-end crystal texture. The cylindrical round body design is stable and not easy to tip over. Both wooden and metal lids are equipped with built-in metal reed stick holes, fitting tightly with the bottle mouth to slow down excessive fragrance volatilization and lock the lasting aroma of essential oil. The minimalist neutral bottle shape matches all modern, light luxury and Nordic home styles, widely adopted by fragrance brands, coffee shops, hotels and customized gift suppliers for aroma packaging.
