Opaque ballet pale peach pink Perfect Bottle Brush Our perfect bottle brush is finally back. Minimal, tall and narrow, this BPA- and phthalate-free plastic brush is perfect for cleaning your bkr. The bristled end makes scrubbing and cleaning hard-to-reach places a breeze. Same perfect bottle brush, now in a new and perfected design. Hot cleaning tips: Your bkr bottles and cups are 100% dishwasher safe on the top rack and sanitize there. If they get gross it’s probably because you need to wash them more often (we do daily) and/or you might just need this perfect bkr brush and some elbow grease. Tutu Color.
