These candle style sealing wax sticks are our own blend based on a traditional resin sealing wax recipe. We have redesigned these candles to burn smoothly with a strong flame to easily make larger seals such as our 1.1" diameter round standard size. You can expect 6-10 seals per candle using a 1.1" round stamp. These are comparable in size to a jumbo sealing wax candle at 5" long x 5/8" wide x 3/8" thick.
