Floating Lanterns. Paper White Box design. Folds out, can put a light inside.
You may need some sand in order to keep it still if using real candles and on a table. Instead of a real tealight you could of course use a battery powered tea light candle. Can also look nice as a table decoration, possibly at wedding receptions and dinners.
If floating it, use the tealight candle it comes with, but use white glue to hold it into place so that it will not slide to the side and ignite it.
Sold in lots of 10 as well as in singles.
Though light, their size affects their cubic weight.
Only smaller sizes available now.
May try to get bigger ones, but it could take some time.
