Colorado State Flag Storage Lids Caps for Mason, Ball, Canning Jars (4 Pack, Wide Mouth) Colorado proud! Store your Colorado herbs and other products in style! Air tight and leak proof. We love these lids for fridge, freezer, and dry goods storage! They are also great for all types of crafts, candles, and storage. If you use Mason jars for drinking or storage, it is essential to have an adequate supply of one piece lids. Two piece lids seal equally well but they are cumbersome to repeatedly take on and off the jar. These serve a similar function to the plastic Ball storage lids but are more durable, seal better, and look nicer. The plastic ones tend to crack and break, especially if the jar gets dropped or tipped over. Available in both regular and wide mouth to fit any jar. Whether you are capping a tiny 4oz jelly jar or a giant 64oz half gallon jar, we have the lid that fits. Hand wash and dry only  these are not dishwasher safe. These storage lids are made of tin plated steel with a plastisol liner. Your entire Mason Jar Lifestyle order ships for a flat $3, or free over $35. Check out our straws and other products! Usually ships in 1 day via USPS First Class from Denver, CO.
