Comments.Text: Scammers seem to be able to do this when they buy sets, remove the minifigs, reseal the bags and then return the box to the store for a full refund - so yes it must be possible. Add the info I just provided as a word of warning to those buying seemingly mint boxes with broken or suspicious seals.

  Use a manual [impulse sealer](https://www.google.com/?q=impulse%20sealer). It consists of a linear heating element specifically for sealing bags in the fashion LEGO parts bags are sealed by the factory. Narrow sealers can be purchased new online for as little as $12-15. It's helpful that LEGO parts bags are relatively small.
  
  I use these devices to reuse bags for various non-LEGO parts storage. There is a dial on the front to adjust the heating cutoff. Depending on the material and thickness a different heating time is needed to ensure a good seal without damaging the plastic.
