Why the Change?

We changed them internally to incorporate an oring groove, instead of using glue to seal it. So, that way a slight change in outer appearance helps to differentiate the two.

im glad they changed it. when i had 1 it was impossible to clean in the groves no matter what i did. so i would have to tell every 1 they were custum grease marks
