I put a tealight in these and light them beside my bed every night.....and I sleep well!!! They give off the most soothing pink/amber glow , are relaxing and good for your health as well!! (How can you go wrong with all of that?) They are heavy so you never have to worry about them turning over during the night. They were packaged well and arrived right on time! They are all hand-cut so are unique...all with different shades of light which gives them a rich, multi-dimensional feel.I have been using these for quite a while....and never want to be without them.....they last forever!!!!!!! I am buying them as gifts for friends for birthdays and Christmas! HINT: use the clear plastic tea lights instead of the aluminum.....that way the candle holder is illuminated all around and even under the tea light. A gorgeous soothing pink glow that will put you to sleep in a heartbeat!!
