You may want to use an Italian charm tool. It is inexpensive and eases the removal and replacement of Italian charms links. An Italian charm tool is not at all a must have, you can even find a suitable plastic object around the house to use as an Italian charm tool. But remember to use an object that does not scratch the charms. Italian charm bracelet links are spring loaded, you compress the spring by sliding the middle of the link across, then hold the next link at an angle you can remove and add links. An Italian charm tool just makes it easier to compress the spring and keep it compressed until your done.
