Color Swatch King: Variants

Highly recommended! I used this app to help me link separate product pages together and create variant swatches for our products since shopify has restrictions on how many variants can be added to one product. The swatches are featured on both the product pages and collection pages and look beautiful! There dev support is kind, quick and helpful. This app has boosted our revenue and UX. 10 out of 5 stars :)
