Some of us do our best thinking when we're damp. Increase your chances of philosophical enlightenment in the bath with a lovely caddy.
Each caddy can be built with a cradle or two for a wine glass, a number of slots to hold a tablet or phone in an upright position, and is designed to rest gently yet securely on the edges of your bath tub. Should you desire, a hook can be created to fit the entire thing over a standard shower pipe when you're not using it! Ingenius!
You may choose a variety of options for details, and each one will be built to specification.
