These amber PET cosmo round bottles come with smooth black fine mist sprayers. These sprayers are made of polypropylene, feature a smooth collar, and clear styrene protective hoods. PET is a great packaging material that is a good barrier to gas and moisture, and also has a good resistance to heat. PET is durable and highly resistant to dilute acids, oils, and alcohols. These bottles could be a great option for packaging many products that should be applied by misting, such as, air freshener, hair sprayer, or body spray.
