I have a Berkeley brush that I use very frequently. Preparatory to lathering, I soak the brush in hot water. Over time the decal has worn/disintegrated to next to nothing. And I am fine with that. This morning I decided to "help it along" by scraping some remnants off with my fingernail. Discovered that the surface directly beneath the decal feels rougher than the rest of the handle surfaces; feels more like where the embossed "Berkeley" is. My question is, was the handle surface left rough to help secure the decal?
