please define undamaged wall? u can post poster and peel it down 99% of time without damaging the wall..but often leave trace of cello tape & etc on the wall...

i blif u can work fine with normal cello tape..but u fold it into double side...near to the edge of the poster...and then put onto the wall... as in if u put the tape near the edge..u still managed to peel it with care next time u wan to take it down...

yes those transparent 1...but try to use the bigger size 1..easier to peel..

and if u failed to remove the cello tape completely...it will be still fine..cos it's transparent ...n ppl usually wont go notice it la...sometimes ppl oso can failed when peel if ma..

how bout my suggestion?

it's not stain pro...juz mayb partial of cello tape remained on the wall...u can peel if off 1..but need extra effort...how can u c stain if it's transparent? and if u fold the 1 piece of tape into 2 and paste in onto the wall..it will be easier to remove 1
