Function really well!
These AromaGlides are awesome.  They work really well and fit my bottles that have the sb logo on the bottom.  I have been experimenting with some green and blue bottles that I have that have YB on the bottoms  So far I have not had any problems using them with these but have not been using this combination long enough to tell for sure that there is not leakage.  But so far they look like a good combination. I find these metal glides distribute more of the oil blend then the plastic rollers, making for a quicker easier application. Great when making roll ons blends for friends and family.<br />I miss read the number of pieces in package.  I have found them other places for a better price.
