The Paper Model requires no glue, all the peices are numbered, and each of the folding-connections are numbered. The guidebook goes step by step telling you which connections between which peices to do. As long as you follow the book you can''t mess up.
The pieces are each colored and it looks really nice. Granted, since it''s made of thick paper, a fall on the floor won''t damage it, but it is significantly more fragile than either of the 2 wood models. I have built one of these myself and am very proud of the result.
Both Wood Models require glue (sold separately). They, too, have each peice labelled and an instuction booklet on how to assemble them correctly in order. (Remember - They''re models, not puzzles!). The difference between the 2 is obvious when you look at the finishd product. The more detailed (and more expensive) one is much more detailed and looks much nicer in my opinion - I have seen both in the Temple Institute''s Store. The only thing I like better about the cheap wood model is that the top of the Holy is separate. By picking it up you can see into the Holy and the Holy of Holies and see the vesels inside (the Menorah, the Table of the Showbread, the Incense Alter, and the Holy Ark of the Covenant) all made by you!
Neither are colored, but painting them would be lot''s of fun.
