I wanted to try out skateboarding, a hula hoop, and a pogo ball to see if I could do them. I've put together a set of these three toys. I bought ones that adults can also use and ride, so you can accompany your child's play and try them out yourself. * Regarding the name, I'm not sure if it's a RipStik, Brave Board, skateboard, or caster board... JD RAZOR Ex mini Length 38cm. * Hula Hoop It's for exercise, but it's a modular design with a wide range of size adjustments, so it can be used by children and adults. Maximum size: Outer diameter 71cm, Inner diameter 65cm * Regarding the name, I'm not sure if it's a pogo ball, jumping ball, or jumping hopper... This type can also be adjusted with an air pump. Width approx. 38cm I practiced skateboarding outside, but I used the hula hoop and pogo ball indoors. They were used by my child, so there is some wear and tear, but they gave up quickly and left them unused, so there are no broken parts and they can still be used. The handles of the pogo ball are made of a soft material, so I'm a little concerned about the dirt, even though it was used indoors. I took a lot of photos, so I would appreciate it if you could refer to the photos for the condition. Since I often give up and stop using all three, I would be happy if someone who wants to try them out could continue to use them. They are large, and the shipping costs would be high if sold separately, so I would appreciate it if I could find someone who wants all three together.
