i dig these from time to time. they are neat but i dont think they have much value. all of the ones i have dug are broken as well. do you find many douch or enima tips? my diggin partner and i have accumulated 5 gal bucket full of them over the years.
Boy, I'm disappointed! The glass ones are fairly inexpensive when they are whole, but what I'd like to see are the hard rubber ones! Now they've got character!
