These talow wax sticks are used together with a wax seal to seal envelopes or messages.
Nice and simple just light the candle wick and drip the wax onto the area you wish to put your seal stamp on, when you have a large enough blob of wax apply your seal to the melted wax and apply pressure for around 5 seconds then gentley remove your seal to leave a lovely pattern.
 
We also supply stamp sets - Here.
