Using these iFixit opening tools is a breeze. For items with a small gap, start by inserting the wedge tip gently into the crack and apply light pressure to breach the seal. If you need to lift or move a part, switch to the hook tip. When using, don't apply too much force at once to avoid damaging the tool or your item. After use, simply wipe the tools clean with a dry cloth and store them in a dry place. This will keep them in good condition for your next opening task.
