Using the JAKEMY 13 - in - 1 Mini Opening Tool Set JM - OP15 is a breeze. First, pick the right tool for the job, like the safe crowbar pry, when you're disassembling your mobile phone, pad, or laptop. Just gently insert the tool into the appropriate opening and carefully pry it open. Be careful not to use too much force to avoid damaging your device. When you're done, make sure to clean the tools with a dry cloth to keep them in good condition. Store them in a dry place away from moisture. And remember, this tool set is for DIY projects, so use it responsibly.
