When my child's eyesight started to decline, I wanted to do something before they needed glasses, so I bought various items at the time. This item was purchased online. My child used it, so there are some minor scratches, but there's no looseness on either side, and I think it's perfectly fine to use (^-^*) Adults can use it too. It's the type that covers the surroundings, so it's recommended for watching TV or playing games☆ It's the type with few holes, so I think you won't feel any resistance (❁ᴗ͈ˬᴗ͈) No smokers, no pets. Instant purchase OK! Due to the thickness, I can't wrap it in much bubble wrap, but I will pack it carefully to prevent damage and ship it anonymously.
