Red extension star 18x18x18cm. Well, exactly measured from tip to tip I come to just 17cm. The plastic material looks very cheap to me and my sister probably wouldn`t want to spend more than 5 on it. At just under 18 minus packaging and shipping, that leaves an estimated 12 euros for the star. That`s just about enough. I have a 3 volt power source from the DIY box and the star lights up almost to the tips. The delivery included a plastic middle section with the light source installed on a fairly short cable, a suitable number of plastic tips to click on and a short T-cable to connect the star to others of this type. It was quite easy to assemble. Even inexperienced hobbyists should be able to understand the enclosed instructions in German. The star now shines as a spike on a yew tree and my sister likes it (she doesn`t know how much it cost)
