Go to Black Widow Bows webpage, click on the Accessories tab, scroll to youth bows, open the link for matrix Jr, order. Repeat as necessary.
These bows cost $89 or $99 depending on which one you choose. They are indestructable. My kids shot them for years and years and so did their friends. Now my nieces and nephews and random other youngsters are shooting them.
They are take-down bows and can go anywhere. My kids killed armadillos, possums, fish, frogs, and assorted other small game with them before moving up to other stuff.
One of the best purchases I have ever madi in my life.
