This is a convenient "precision screwdriver for glasses" for when your glasses screws come loose and are about to fall out. It comes with a key ring and is small, so you can just hang it somewhere on your belongings and use it in case of emergency. It supports Phillips, flathead, and hex screws, so it works with most glasses screws. ☆Product Details☆ 3-in-1 Precision Screwdriver for Glasses Quantity: 3 Material: Aluminum steel Usage: Can be used for screws on glasses, sunglasses, watches, mobile phones, etc. 【Notes】 ① We cannot guarantee that it can be used for all screws. If it doesn't fit or is tightly screwed, stop using it before the screw head is stripped. We cannot provide a warranty if the screw head is stripped, so please use it at your own risk. ② It can be slippery if you are not used to it, so be sure to protect the lenses when working near them to avoid scratching them. We cannot provide a warranty if the lenses are scratched, so please use it at your own risk. ③ If you want to tighten the screws properly, have them adjusted at an optician's. We recommend using this only as a temporary measure. ④ Please refrain from purchasing if you are overly concerned about potential problems. It is safer to have your glasses adjusted at an optician's except for temporary use. ◆Must Read◆ To reduce the burden on postal workers, weekend, holiday, and next-day delivery are no longer available.
