The BMI Accessories Funnel is a great tool to have handy at all times. This funnel will help you easily pour products into your favorite bottles without having to worry about spilling! It is made up of polypropylene (PP), making it strong enough to stand up to virtually any detailing products. These funnels are reusable for years to come unlike many cheaper versions! After use, simply give them a rinse with soap and water and you are ready to use it again. This is also a great way to measure out the products you buy in bulk, or the ones you want to dilute. Concentrated products represent the best value and using this funnel to dilute them to the proper ratio is a great way to save money!
