This is a set of reading glasses that belonged to my grandmother. I don't know the exact strength, but I believe it's 2.0 or higher, so it might be quite strong. This is recommended for anyone who needs reading glasses, regardless of the strength. Available for immediate purchase. Feel free to make offers on the price. Purchased within the last 15 years and stored in a dark place after decades of use. There is some soiling, and it is not as clean as new, so please be aware of this if you are sensitive to such things. When packaging, I will take measures to prevent water damage and breakage.
