Manufactured by Mak Magic 2001 Model
The silk cabby is a wooden box with two doors, when opened, reveal an empty chamber with two large holes at opposite ends.

It can be turned completely around proving it is empty.

Now, three white silks are pushed one at a time in the box and each emerges a different colour out the other side!

These coloured silks are then pulled through the box and emerge tied together!
The box can be shown empty any time.
Many other effects are performed with this versatile box.
