All you need is a swimming noodle, like the ones used for pools that sell for around 1-2$. That is a lifetime supply. Now say you need a holder for your sally hansens, You just cut a piece about 1 inch high and then cut a hole for the bottle in the center. The hole should be slightly smaller than the bottle to grasp the bottle tightly.
This prevents the bottle from tipping over and spilling all over your bench if you accidentally bump it and you can just squeeze the foam while you unscrew the lid. ( a plus for larger hands)
hope it helps....someone??
