WILDREAMBrown Teddy Bear Plush , Super Cute & Huggable Stuffed Plush Animal Toy

Q: Does this fit a Build-A-Bear close

I would think it fit Build a bear clothes or be really close. This bear isn't as " firm" as BAB bears but just about the same size

Q: Is it small enough to fit in a shoe box ? I’m mailing it to a friend and the box is small

I don't know the size of your "small " box. This will not fit in a small childrens shoe box but an adult size 9 1/2" shoe box should work. Or you can look around the grocery store for boxes larger than what you have. It's worth the effort because it is a precious little Teddy Bear.
