There are a few search results related to black nail design, but they provide different types of information. Here is a summary of what I found:

• A Byrdie article suggests a black and white negative-space nail art trend, which uses black, white, and clear polishes in half-moon shapes.
• An Amazon product page for JXH Black Gel Nail Polish provides information about the product, including its package dimensions and weight. However, the customer reviews are mixed, with some positive and negative comments about the products thickness and quality.
• A Real Simple article provides 11 edgy black nail art designs to try this season, but it doesnt provide any details about the products used.
• Another Amazon product page for Arte Clavo 15ml Gel Nail Polish provides information about the products ingredients, which are natural resin and non-toxic. The product is cruelty-free and never tested on animals.
• A Fed & Fit article provides information about non-toxic nail polish brands and ingredients to avoid. The article mentions that some nail polish brands, such as Essie and Revlon, are "3-free" (free of toluene, formaldehyde, and DPB), but they still contain other ingredients that are not recommended. The article recommends some non-toxic nail polish brands, such as Zoya, Ella+Mila, and Olive & June.
• A CDPH booklet provides information about how to work safely with artificial nail products, including finding out what chemicals are in the products and how to protect yourself from exposure.
