Spiral hinges on the side slide off easily. While I put it in a lightbox. The round lid slipped off its hinge and fell to the floor, glass shattering everywhere. It took an hour to remove the pieces. Take out the jar just in case. After inserting the hinges into the lamp, check again whether the hinge is fixed laterally, return the glass to its original position and lift it. The glass was very heavy and should be plastic in my opinion, especially with the shower cover.
