My wife uses shampoo bar's from the store Lush. The problem is when you buy them, they do not come with any container to hold them.
At first we tried storing them in the little black pots that other Lush products come in. I drilled some holes in the bottom of the black pot to let the water drain out. The pot helped to stop the shampoo bars from getting wet while taking a shower but the drain holes did not allow enough air to fully dry the shampoo bars.
I made up these trays to support the shampoo bars inside the little black pots and allow the water to drain off easier. You place the tray with the spikes up. What works out nice is that the spikes allows you to stand the shampoo bar up vertical if you need it to dry quicker.
