they quit making them like this a couple of years back because the tiles can easily get broken!
It is better to use a bag of sand or walnut shells and make that a pin cushion area.
I will try to get a pix of mine to show you...it has a muslin bag filled with sand inside of a ziploc that is duct taped all around then wrapped in batting and puffed on top with more batting to make it a pincushion.
I love it and make them for all family, friends, etc.
You can buy the plastic tubing at the hardware store.
