If there is tape on one of your designer boxes don't give it a second thought. Just get out your blow dryer and use it to safely remove it without tearing. Use the high heat setting and s l o w l y peel it off.

This box was really taped down .

On the back too.

Now apply heat with the blow dryer and ...

Voila! All gone...

Even from the back!

Hope this has been helpful. If you need to ship your doll I would recommend not taping the original box. Instead you can slip it into a plastic bag to keep it in good shape for the next person.
