Perri, a reviewer, is impressed with the Shadow Stix in Walnut ave color by ColourPop. She mentions that the new formula is a significant improvement from the previous version. The shadow stick is described as extremely creamy and glidey, making it effortless to apply. Perri even used it to create a wing and found it easy to smudge. She believes that the product will dry down without creasing and appreciates its versatility for both liner and all-over lid use. While the swatch appears as a reddish-brown, blending it out reveals a cooler tone. Perri suggests that a truer red tone color, like one of the purples in the range, might be preferable. Overall, she finds the Shadow Stix to be a fantastic multi-use product.
