I have several of the Fiskars trowels. The handle is hollow. If you pull off the orange plug, you have a small cylindrical compartment. It is just the right size for a small roll of toilet paper! I don't think that it is waterproof. I haven't taken the time to test it, however. BTW, I made a small hole in the part of the plug that is inside the handle. I tied a piece of carpet thread to the plug & the toilet paper so it (the toilet paper) can be pulled out when you remove the plug.
