We have tried: We glued the self-adhesive back part to various materials (paper, pvc foil, glass), where it held well. Then we tried to peel off and stick the parts of the hook + plush. After doing it several times, the adhesion of the velcro decreased. After 50 detachments and attachments the counterparts held only weakly, after 130 of them the velcro hook held only two threads of the counterpart - plush.
