We designed our Supersized Warmies for really big hugs — so big, in fact, that they’re too large for microwaves! Instead, we made them with an easy-to-remove heat pack that can be microwaved (or chilled) for your comfort. These extra-large Warmies are made to soothe or warm your hands and can double as a huggable pillow. All other Warmies styles can be placed directly in the microwave.
