Your bid wins two very classy new smallish curved shape cathedral glass hand made lamp shades. These just fit straight onto your common or garden plastic ceiling lamp holder (no electrician needed) or could fit anything that has the common 29mm threaded lamp holder eg. table lamp or wall lamp or maybe even a 3-light pendant. OR they can fit 38mm Edison lamp holders in some cases as well. Seller can also offer nice small round LED bayonet bulbs as well if desired. They are 20cm diameter (seller MAY have more than 2 if more required -check if more needed) Cathedral glass is hand-made glass sheet that has the colour in the glass - they are not stained glass or coated glass. Please bear in mind that these are handmade, not machine made, but they are pretty amazing. Check sellers other listings for other Tiffany style lamps (there are 30cm and even 40cm to match the 20cm -8 inch ones)
