Hi Steve,

Thank you for contacting Mearto with your appraisal inquiry.
The glaze treatment on these charming figures is what's known as "Flow Blue," a style of ceramic decoration that originated in England in the early 19th century. Known for its blurred, flowing blue patterns, the technique was created by intentionally allowing cobalt oxide to bleed during firing. It typically adorned plates, vases, and other decorative items.
Small figures such as these are in plentiful supply with significantly less demand, which keeps prices on the (very) modest side. As an example, two pairs of related Flow Blue Dutch Water Boy and Girl - all made in Japan - sold for just $25 when auctioned in 2017 (https://www.liveauctioneers.com/item/52800390_2-set-vintage-flow-blue-dutch-water-boy-and-girl).
Based on the photos and information provided, and subject to examination, this is:

A pair of vintage Flow Blue Delft style Dutch Water Boy and Girl porcelain figurines
