If it's not the large Mario Luca Giusti; Milly Tumbler, I'd be surprised. If not, it's a very close approximation. I believe they are heavy acrylic and not actual glass/crystal. Example: Mario Luca Giusti Milly Large Tumbler Clear - Set of 2
Just got my shipment. Regardless of preference of film series, this design was great and this replica is amazing. Solid and substantial. Can't wait to do finishing touches on it. Thank you!
Do what Thomas said and contact JWJR. He lives about 5 miles from me and I've had his lights and sound in a proton pack, models and other doodads for years. He really knows his stuff. He already hit me up for lighting my soon-to-be built "A". :D
