I bought this set because I wanted the one for your back. The other 2 were a bonus for me. I can't reach my back most people can't. I have really dry skin and it itches all the time. This scratches off the dead skin so it doesn't itch so bad. Loofahs remove dead skin and deep down dirt from your body. They promote circulation and leaves your skin looking smooth and glowing. The 2 sided one for your back is loofah on one side and soft terry cloth on the other. It's 4 inches by 35 inches. You can hang it to dry after you are done showering. The other 2 in this set are the same size. They are a little more that 4 inches long. You can use these loofahs for more than just bath time. You can use them for dishes to get the hardened food off, scrub floors, tubs, anything that you need scrubbed. Use your imagination, there are tons of uses for these things. Crafters will loves these too.
