Nibble protectors

[InkMinx]

One of my piggies has decided to start chomping on the coroplast. Does anyone know where I can get nibble guards other than Kavee? I'm sure there is some stationary binding thing that would do the same thing but I don't know what its called to look for

Try googling for 'plastic slide binders'.
Or if you go to a large stationary store they should have them.

I got mine on ebay.
