During the summer months please keep in mind that soy wax melts and so do lip balm.  So far I've only had one order of candles to melt in over ten years.  I make every effort to package things so they should be well insulated, this being said please do not allow your package to sit out in the heat and the sun for any length of time or they could melt.  There shouldn't be any issues but if there are please contact me ASAP to arrange either a refund or a replacement.
