The Seasonal Box

Yes, it really is easy. Each refill is designed to become a candle with very little effort. There are no special tools, no complicated setup — just a few quiet minutes and a candle made by you.

How it works:
Open the candle bag and remove the wick, wick holder, and instruction card. Place the bag of wax on a microwave-safe dish and heat for 2 minutes, or until fully melted.

While the wax melts, center the wick in your chosen vessel. We recommend a heat-safe, stable, non-porous vessel about 3 inches in diameter — or simply use one of our Forever Vessels.

Pour in the melted wax, adjust the wick so it’s centered, and let the candle set for at least 2 hours. Trim the wick to 1/4 inch, light, and enjoy.

When you’re done, compost the empty bag at home or through industrial composting.

Yes. Our candles are made with 100% natural coconut-soy wax, clean fragrance ingredients, and no paraffin, parabens, phthalates, sulfates, or harsh chemicals.

Every scent is crafted with a blend of sustainably sourced essential oils and safe fragrance oils, and is IFRA-certified to meet global fragrance safety standards.

You can learn more on our Ingredients & Impact page.

The Seasonal Box subscription offers 45% off your first box, and 20% off every box after. Plus free shipping, always. You can cancel, pause, skip, or swap scents anytime. If you'd like to gift a box to a friend for a season instead of receive it yourself, that is also possible. Manage your subscription in your account, or simply email our customer care team at support@siblings.co and we will take care of any changes for you.

Scent is personal, and we want you to find one (or many) you truly love.

If your candle is unused, you can return it anytime — and your first return is on us. Think of it as a little breathing room to explore, discover, and choose the scent that feels right in your home. Learn more about our Happiness Guarantee.

If you'd like help deciding on a scent or are looking to start a return/exchange, we are always available at support@siblings.co

Because it feels better from the first light to the last. Premium fragrance, clean-burning wax, and a handcrafted vessel made to live in your home long after the (first) candle is done. Just refill it and keep the ritual going.

Because over time, it becomes more than a candle.

It’s there for slow mornings, quiet evenings, dinner on the stove, books half-read, baths run, rooms reset. Season after season, scent after scent, it stays.

Handcrafted in Portugal from 95% recycled clay, the Forever Vessel is made to be used again and again — not tossed when the wax is gone, but refilled as part of the rituals that make a house feel like home.

Your first Seasonal Box includes a Forever Vessel, designed to fit our refills perfectly — so your candle looks beautiful, burns evenly, and is easy to refill season after season.

You can also use a vessel you already have, as long as it’s heat-safe, stable, non-porous, and about 3 inches in diameter. An old candle jar, favorite ceramic cup, or thrifted find can all work beautifully if they’re made to handle heat.

Not sure if your vessel is heat-safe? Carefully pour boiling water into it first. If it doesn’t crack, leak, or show signs of damage, it’s a good candidate for a candle.
