The Kids Tri Blade is one of the easiest boomerangs to learn to throw from age 10 on. It has a very short boomerang range of 10-15 meters and is very easy to get to return. It uses a soft wood but parental supervision is still needed, of course. Please note that colors and patterns may vary.
Kid's Triblader RH has a rating of 5.0 stars based on 2 reviews.
