Effective handwarmers with the bonus
Effective handwarmers with the bonus of three heat settings. The two sides snap together with some force. Made me think of crocodiles without the teeth hazard. Just as well, no teeth that is, when I left a finger in the way. The warmers arrived expediciously and were immediately loaned to spouse who was outside fixing Christmas lights to the hedge. Especially valued when the neighbour held up work for a prolonged chat.
