How to Get a Jeweller's Loop

Much of jenny's advice revolves around being able to access nature, trees and animals. But what about people who might not live near a park or some other green space? I ask jenny, how can they put these ideas into practice? If you can get a jeweller's loop, or a hand lens, as they're sometimes called, it's like a little tennyx lens that folds out if it's in your pocket. And i've been upsessed with this thing for the last year. You can use it to look at anything. Even moss and plants are great but even any surface really is fascinating.
