To use these Kiddush cups, simply pour your favorite wine into them when it's time to say a blessing according to Jewish traditions. They're great for Shabbat, holidays, weddings, or a bris. Just make sure to handle them carefully as they're a bit heavy, weighing 2.5 lb. After use, wash them gently with mild soap and water. Keep them in a safe place, away from other hard objects to avoid scratches. These cups are made in the US, so you know they're of good quality. Enjoy using them to add a touch of sanctity to your special occasions.
