Rainbow Craft Ninja Warrior Slackline Ninja Fist Holds - Kids Ninja Backyard Ninja Training Equipments, Ninja Accessories for Ninja Warrior Obstacle Course, Ninja Fists, 3-Pack Monkey Boxing Hold

Just attached these to my jungle gym. Really sturdy and super easy to install. I just kind of wished there was more than three. Seems like it's made from decent material, can hold a decent amount of weight.

These are a great addition to my kids ninja set up in the basement. Easy to hang from some eye hooks in the ceiling.

Well made - heavy - great for key’s self defence.

My kids love them so much, and they are very sturdy, which is also reassuring to me.

I didn't realize how big they were. I can't wait to knock someone in the head with one.

Very easy to install on our existing line. The first time my daughter used it one of the knots came undone. My husband had to tie it again and she said it’s just not the same as the other ones.

We have purchased all the other Rainbow Craft Ninja accessories and I would give the rest of them 5 stars. These holds, unfortunately, are worthless. Within 5 minutes of my 5-year old using them, one of the knots loosened and extended the hold multiple inches and another knot came undone. These were poorly thought out and should not have made it to market based on their quality. Don't buy if you want your kids to actually use these.

The kids love these! If you've got small children who enjoy playing on jungle gyms or other climbing activities, you can put together a fun obstacle course if you've got some sturdy trees and a slack line. These handholds are a great start for swinging around, and you can collect and add more obstacles to make it more varied and interesting.
