I've seen those on a site before and I think they're a joke.
A pin cushion is so much cheaper......I use one of those magnet type. You don't have to stick it in a cushion, just toss the pin a little in the direction of the magnet and there it is.
They are wonderful if you spill pins, real easy to pick up.
I use a pin cushion for needles and little odd stick pins but not the ones I use daily.
