Purchased for exam preparation. I mainly used these for commuting to cram school, so they show considerable wear, but I think they'll be fine for school. This is a combined listing of items from Familiar and GU. ① - familiar - 18 cm - Black ② GU 19 cm Black Shipping will be via regular mail (without a box) if you're okay with a compact size. These are offered at a low price, so please check for any damage beforehand. Since they show signs of use, I don't recommend purchasing if you are concerned about minor details. Thank you.
