Buff is a theme for small body-care and bath brands that sell to more than one country. Its signature is the Steam Glass: a fogged-up shower window on the home page that shoppers wipe with a finger or a mouse to find the products on the shelf behind it, then tap to add one to the bag. Leave it alone and it slowly steams back up.

The home page is built from selling sections: a split hero with a shoppable product tag, a scent ribbon, tabbed bestsellers with quick add, a two-question product finder that suggests a product and something to pair it with, ingredient cards linked to the products that use them, numbered how-to steps, sets, tagged customer photos with shop tags, a gift card banner, questions and a newsletter sign-up. Standard sections come too: a slideshow, image with text, feature columns, a video (a muted background loop or a player), review highlights from your store reviews, a visit-us block with opening hours, a collection list as a grid or a carousel, and rich text.

You can choose between two header layouts (logo in the middle or logo on the left) and three footers (columns, a sign-up band, or a compact one-line footer). Every footer has a newsletter form. The header takes extra links, and you can switch the search, account and wishlist icons on or off and keep the header at the top while scrolling.

The product page is made of blocks you can reorder or remove: breadcrumbs, title, rating, price, short description, volume prices that light up for the chosen quantity, options with quantity, Add to bag and Buy now, Notify Me, delivery and returns notes, how to use, ingredients, specs from metafields, your own text, any metafield, and app blocks. The gallery can be a collage, a stacked column, one photo with thumbnails, or a carousel, on either side, with the details kept in view while scrolling. Variant pickers show as segments, cards or icon chips. Sold-out variants show a Notify Me form by email or text message, and gift cards get a recipient form with a message and a chosen send date.

For the cart you choose a side drawer, a wide drawer with the summary beside the items, an added-to-bag card, or the cart page, and what happens after Add to bag: open the drawer, show the card, show a short message, or go to the cart page. The cart page can have its summary beside or below the items. Free gifts and discount suggestions from your store's discounts appear in the drawer and on the cart page with an add button. Product cards come in three styles (photo, framed, centred) with settings for image shape, a second image on hover, vendor, rating, colour swatches, quick add and text alignment.

For international selling, Buff includes a first-visit country prompt as a corner card, a top bar or a centred dialog, a country and language chooser with currencies and search, and a short note after a switch that confirms the new country and currency. Every phone field has a country picker with dial codes and example numbers. Collection, search, brand and vendor pages share a filter panel with every filter display type, sorting and paging; predictive search and search within a collection can be switched on in the theme settings. Accounts, sign-in that follows your store's sign-in settings, order tracking, a wishlist and a password page are included. Buff ships in English, German, Spanish, French and Italian, in two styles, Buff and Butter.
