Do not keep anything on top of the brooch as the varnish may take on the pattern of the object. The impression will be visible when light is reflecting at an angle.
This can sometimes be repaired – the varnish bounces back on its own but it can take months – best to avoid.
This is a piece of art. Just like you wouldn’t sit on a painting, scratch it on purpose or try to bend it, use similar care with this piece.
Ideally, store flat wrapped in butter paper that comes in the packaged box, which is shipped to you.
Do not wrap in plastic. Plastic will stick to varnish / acrylics & leave an impression.
Keep away from solvents like isopropyl alcohol and perfume. If such contact is made by mistake, do not try to wipe it. Leave it alone to dry. Do not touch it. The alcohol will evaporate and the varnish will dry on it’s own.
Excessive heat or cold are best avoided.
If it gets dusty / linty, wipe gently with soft cloth.
