3.8mm セキュリティドライバー NES・SNES・N64・ゲームボーイ対応

Took apart my old N64 game to swap the battery, and this tool fit the security screw like it was made for it. The tip is sturdy and didn't slip at all.

The bit gripped the SNES cartridge screw perfectly without any slipping, and the handle gives just enough leverage for a tight turn. I finally cracked open my old Pokemon Yellow to swap the battery, and it worked like a charm. Definitely glad I grabbed this tool for the retro game collection.

Finally got around to swapping the dead save battery in my old Pokemon Yellow and this thing made it effortless, the tip grips those tri-wing screws perfectly without any slipping. It's a solid little tool that handles all my retro cartridges, so I'm glad I picked it up.
