Since it is an acrylic material, it is important to wear with care and not place pressure on the piece. Jewellery which is double in thickness will be much more durable. We would recommend a base layer on all custom word necklaces. I would advise not to get items wet or wear in the shower to avoid chain tarnish. A silver polishing cloth will brighten up the chains if dulled over time and also acetone nail polish remover will clean the plastic of any dirt or dust. If you happen to get scratches on your acrylic item, a plastic polish such as xeropol would be ideal to use. Avoid any chemicals such as perfume deodorant or hairspray on items which contain Swarovski crystals.
