This is a rechargeable mini screwdriver from Nafco. I opened it and charged it immediately after purchase, intending to use it, but I never ended up using it. I haven't even touched the included bits. I have a screwdriver set I bought at a 100-yen shop that meets my needs, so I probably won't use this one in the future, which is why I'm selling it. I plan to ship it via Letter Pack Plus.
