Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.
