If I buy any BF-Synthetic product this year and don’t use it all, will it still be good for next year?

Yes, each and every one of our products have an infinite shelf life and basically never spoil (note however, that odor and appearance may change some with age). Kevin Kreh (our founder) was using 5-year-old product to take a monster buck while hunting in Kentucky. And thus we know that age makes absolutely no difference in overall performance. Plus they require no additional or special care, such as freezing or refrigeration. We also know that overall product performance is unaffected by exposure to extreme temperatures or even direct sunlight. Enjoy new benefits and greater scent results without hassling with the old problems with “natural” scents.
