Oskar_van_Deventer Hi AnelnisxXx, The title of this product is "Personalize your Treasure Chest" and the description starts with "CAUTION: CENTER ONLY! This custom center goes with ...".

Feel free to contact me via if you have any further questions. Oskar

Oskar_van_Deventer @galiliosharma Feel free to send your request for lower prices to Shapeways. Shapeways has put a huge effort into their current pricing model, which they claim is cost oriented. However, they may be compelled to give you a discount if you place a huge order.
