Cels Forum

The problem with using a hair dryer is that cels are VERY
sensitive to heat.  they can warp just like that if left under
a heat source of that kind.  plus the Studio Pierrot stickers
are not of the paper kind, it is a plastic clear sticker.
that will have a higher heat threshold than a paper sticker.
It's best not to put heat near your cel.  If you REALLY want
it off, you could peel it of with some effort of your fingernails,
and the Studio Pierrot stickers arent old, they were applied
this year to commemorate the 20th anniversary.  The stickers
were applied with a strong adhesive though.  Trying to remove
this sticker runs the risk of shock and damage to your cel, no matter what angle you try to remove it from.
