10 1/4'' utility and sink brush, polypropylene block, filled medium yellow polyester, resin set. This is a real must-have in any demanding kitchen. With a small surface area and short easily gripped handle, it is a really effective pot and board scrub, and spot cleaner. It is perfect for cleaning off chopping boards, soft enough to get in grooves, not too 'flicky', resilient enough for a good scrubbing action without crushing. See also #B1606, DW1090.
