Naturally, you will be able to find suitably-sized frames for the jigsaw puzzles with between 500 and 1,500 pieces in any major retail store, otherwise you can buy a made-to-measure frame.
PLEASE NOTE: for technical reasons, there may be a difference of a few millimeters between the dimensions printed on the box and those of the actual finished jigsaw. Therefore, we suggest finishing the jigsaw puzzle first and measuring it before choosing your frame.
