Strange title, strange products… The AIL-B120 and AIL-B130 are two fat balls (uh?) measuring 20cm and 30cm, made of a soft material (not getting any better), and changing color depending on the ambient sounds (this is starting to go in the wrong direction). What is this product for? Quite simple, you’ll have two large balls at home that change color depending on the noises around, to produce a Zen atmosphere… Rocco will be happy to know that!
