From the release:
We have a new tool that should help tame those pesky magnets. This device allows you to put a magnet precisely where you want it without getting glue everywhere or messing with tweezers.
Simply press the plunger to reveal the steel rod inside. Pickup the magnet and move it into place. Once you release the plunger the steel rod retracts into the brass casing and lets go of the magnet. You don't even have to wait for the glue to try! Great for epoxy users.
The tool is designed to work with large and small magnets. All the way down to 1/8"! You can use if for even smaller magnets but you'll have to wait for the glue to dry or else they will be retracted into the tool with the steel rod.
