Giant 4-1/2" x 4-1/4" x 1-1/8 box contains about 125 pieces of high quality fully marked 5VDC operated 4 lead crystal oscillators. Each has its frequency marked, each is brand new and 100% prime! We checked a couple of boxes and found at least 15 different types. Several of these are worth more than the cost of the box! Product contents will vary from box to box and picture shown.
