Want to make a historical model without glue that you can play with?
Try COBI!
Their building blocks are of exceptional quality (yep, even comparable to LEGO and they are compatible) and they are in partnership with The Tank Museum in London as well as the World War II Museum in New Orleans.
If you've met Bret you've seen his LEGO ring. He'll tell you how continually surprised he is by COBI - and Play Favorites wouldn't carry it otherwise!
Some of COBI's big perks: there are no stickers all details are printed! Also, the models are 'swooshable' the planes can't fly, but you can swoosh them!
COBI's historically based models inspire accidental education and will excite your local historian!
