The miniatures inside are glued in place, but it should be possible to remove them for customization. They are housed in wooden boxes with glass that fits in from the top. This item has been stored for a long time after purchase, and has been kept in a chest of drawers. The large wooden box has a scratch on one side. Sizes: Large approximately 20.5cm x 15.5cm x 8cm Small approximately 15.5cm x 15.5cm x 8cm Please refrain from bidding if you are concerned about minor details or are overly sensitive. Thank you for looking.
