This is a Stiga table tennis backpack. Please refer to the manufacturer's catalog for details. I bought it two months ago and used it a few times, but it was too big for a working adult who doesn't practice much, so I'm selling it. It can hold a lot of luggage, so I think it's great for junior high and high school students who go on trips. Socks will be included as a bonus, size 25-27cm.
