Introducing the MTM Primer Flipper Square designed to make filling primer pick-up tubes a breeze. With its innovative square shape transferring primers from traditional factory packaging has never been easier. This product offers two convenient lid options: a snap closure for spill-proof storage and a 90-degree rotation for a smooth friction-free lift-off removal. The lid features a marking area to indicate which primers are in the tray and its clear-view design allows for easy identification.
