My son is in the 6th grade of elementary school, and he only used these a few times because I bought him a size that was too small. My daughter is in 2nd grade, and they should fit her, so I think they're suitable for grades 2, 3, and 4. They haven't been used much, so they're in good condition. I think they cost around 9300 yen. - Color: Black - Model Name: Zett Prostatus - Material: Leather - Size: Right-handed thrower Thank you for looking.
