16 the thickness of switchable d u00e9cor 18 is generally between 6 mil 006 inch and 30 mil 0 030 inch preferably 12 17 mil d u00e9cor 18 also includes an opening 48 sized commensurately with openings 24 36 of fixation sheet 16 and case 14 respectively unlike fixation sheet 16 switchable d u00e9cor does not include an adhesive rather switchable d u00e9cor is securely attached to case 14 by non permanent adhesive 34 on fixation sheet 16 the adhesive characteristic or u201c stickiness u201d of non permanent adhesive 34 is dependent on the materials it contacts that is non permanent adhesive 34 may have a stronger adherence to one material than a different material therefore depending on the particular non permanent adhesive that is being used the particular materials selected for making fixation sheet 16 and switchable d u00e9cor 18 are generally selected such that the non permanent adhesive will adhere more strongly to fixation sheet 16 and will adhere less to switchable d u00e9cor 18 by selecting the appropriate non permanent adhesive in conjunction with the materials for fixation sheet 16 and switchable d u00e9cor 18 the switchable d u00e9cor is more easily separated from fixation sheet 16 and the non permanent adhesive more securely retained on the fixation sheet switchable d u00e9cor 18 includes a graphical image or design having black and white color text names patterns images photographs or combinations of such designs for example the designs can include names logos slogans advertisements or combinations of such graphical indicia the designs may be customized by the user or be provided by the manufacturer of system 10 the design can be provided onto the substrate supporting the design by printing silk screening etching etc in certain embodiments switchable d u00e9cor may have a luminescent.
