These drip candles are seriously fun! You get 25 candles in this pack, each one in vibrant rainbow colors that'll make your drip candle mountain look amazing. Here's how it works: you stick a candle in an old wine bottle or any holder, light it up, and watch as it drips wax everywhere creating these cool patterns. Each candle burns for about 20-30 minutes, and when it's done, you just place another one on top of the melted wax to keep building your creation. They're 0.75 inches in diameter and 6.5 inches tall - perfect fit for most wine bottles. Oh, and here's a cool bonus: they glow fluorescent under blacklight! They're unscented and each one weighs about 1.5 ounces. Whether you're starting your first drip candle project or adding to an existing one, these colorful candles create such a neat visual effect as they melt. Super fun for parties, decorations, or just as a creative hobby - the possibilities are endless with these drippy candles!
