A pair of yellow handmade acrylic wall lamps. The sconces were designed by claus bolby and manufactured by his own company, cebo industri. By experimenting bolby discovered a technique allowing him to introduce bubbles into the acrylic, which adds a special layer to the material. The lamps are completely original and in excellent condition. They have not been affected by the heat of light bulbs and in order to keep them in this excellent shape we recommend using led lights or light bulbs of no more than 40 w. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
