Actually, I found out AFTER I opened the stupid
package that this was clue and not really "tape".
 ~_~  
Would regular clear office tape be "okay" for the
cel?  I put as little as possible on the cel (just
to hold it in place on the mat boards).  

I have been searching around for acid free tape
with no luck at all.  Does anyone know where I can
find this??  ~_~
