24x13mm Green Bakelite? C-shapes

Price listed is for 30 pieces of bakelite. These are bakelite c-shapes that are green and either blue or gray (pictured). There is some variation in size, but they are approximately 24mm by 13mm. They are partially drilled on one end of the C. One piece has a small chip missing on one end. WE PURCHASED THESE AS BAKELITE. HOWEVER, THEY ARE NOT TESTING POSITIVE WITH SCRUBBING BUBBLES.
