... Sure it's Spielkram but just for a colle Party right. For 2 euros per ring of course I expect no mega quality. I have ordered a total of 15 pieces and all functioned. My daughter has organized a disco party for her birthday and the girls (and even boys) were thrilled. The rings have buttons for on and off, although this slip in wild like to use, so you have to fumble a bit and looking to turn it off, but they can be used again at the next party. I would certainly order again the next party and as I said, the effect is bombastic when you're on such a "kitsch" and "blinkeblinke". The girls had wrapped the rings as scrunchy around the braid and adapt them to large and small fingers. Strong buy recommendation - a must for the next party !!!
