Been researching a new brush online and noticed Mason Pearson being a highly recommended luxury product. Peter of Kensington is an official stockist for the brand through the Australian distributor.
Only this pink version of the nylon and boar bristle brush seem to be at the best value IMO.
Other nylon and boar brushes at discount (but not at best value):
Ivory Popular Bristle & Nylon Brush
If you look for the product on the Peter of Kensington eBay and use the 5% off code PASTA5 you can partially negate the shipping cost.
For sizing differences between Popular and Handy, refer to here. The TLDR, the Popular is bigger for people with longer, more full hair. Handy is smaller for people with shorter hair than the people with longer hair.
