SHARP Electronic Dictionary PW-A8010T Operation confirmed. It's from around 10 years ago, as I used it around the time of the school festival. The case is sold separately. I attached Velcro to the back and used it with a case, so I've attached Velcro to the main unit. It would be messy to remove it, so I think it's best for someone who can use it as is. Alternatively, I recommend purchasing a similar case. Stored at home. #ElectronicDictionary #SHARP #Student #Overseas #Study #Semiconductor #Parts
