It's been around for years . It's called the Kent Infinity Silvertex. It costs around £12-£13 and has a cheap moulded handle and older type fibres. Very strong back bone ans fairly soft scrubby tips. As synthetics go it is quite unique in face feel but it does look and feel cheapo cheap cheap. It works as it should though.I didn't realize Kent was offering a synthetic--or is this a re-knot? Either way, it's a very nice brush.
