What are HotSpots™ Corn Bag Warmers? HotSpots™ Corn Bag Warmers are microwavable heat sources that you can carry in your hand or pockets on chilly days. Use them in place of a hot water bottle, electric heating pad. You'll find HotSpots™ superior to both. Aren't HotSpots™ Corn Bag Warmers just like any corn bag on the market? Yes, if you consider a Cadillac "just the same" as a Yugo. We make each HotSpots™ Corn Bag Warmer from the finest pillow ticking material available. This means that with proper care, your HotSpot™ Corn Bag Warmer will last for years.  You didn't just buy them overseas and are re-selling them? Absolutely not. All HotSpots™ Corn Bag Warmers are proudly made in the United States of America. I don't have a credit card, or don't want to use it on line. Can I send you cash or a check? The on line payment is quite safe. It goes through a secure payment site ( PayPal ) and I never personally see your credit card number. If it's that important to you, e-mail me and I'll see what we can do.  How long can I expect the corn bags to stay warm?  That depends on the size of the bag, the outside temperature, how hot you heat them in the first place, etc.  However, as a rule of thumb, the small hand warmer size should stay warm 20 to 30 minutes, and the medium and large sizes from 40 minutes up to an hour. Again, these are estimates; your mileage may vary. What if it gets dirty? Try to not let that happen. The HotSpots™ Corn Bag Warmer itself is not washable. That's why we provide a replaceable cover with each one. If the HotSpots™ Corn Bag Warmer becomes soiled, you can spot clean it with a damp cloth and allow to air dry. If that isn't sufficient, then we recommend replacing your HotSpots™ Corn Bag Warmer with a new one and always using a cover. I need some special sizes, custom colors, large quantities, etc. Can you help me with that. You bet we can. Please e-mail me at info@CozyCornBags.com and we will do our best to help.
