yeah it will bend or wrap without sticking ... an option is to stick the pad on the inside of the envelope packaging .. just reverse the flaps and lock it in and this keeps the nano secure when you want to stow it away

for the glue ... ur the 2nd person to tell me about it . soap will be able to remove it ... the glue is actually the best we have at the moment after testing many different types to ensure that it sticks ... fail rate so far is minimal compared to when we first launched the nanoblok a few years back but thanks for the feedback and we'll look into alternatives as always
