  • Amethyst, Tiger's Eye, Obsidian, Rose Quartz, Clear Quartz, Labradorite, or Moonstone

Each heart is unique and finished by hand, complete on its own.

Care note: hand wash only, avoid submerging the stone detail.

One Winged Straw - Reborn
$111.00

The original silhouette, remade. Reborn takes the signature wing — made for cacao ceremony and ritual use — and elevates it: a hand-placed gem or pearl set esoterically, each stone chosen to embody c♥nt. Where its previous form is elemental, Reborn is refined: the same hand-shaping, the same ceremonial c♥nt, brought forward into something built to be an heirloom.

Available across the full M31 palette, in Stainless Steel or Borosilicate Glass — harm reduction by materiality, all straws are chemically non reactive.

Choose your style:

  • Material: Stainless Steel or Borosilicate Glass

  • Size: 3"

  • Accent: Gem, Stone or Pearl inlay

  • Color: Black, Silver, Red, Blue, Green, Clear, Pink, Grey (Pink metal coming soon)

  • C♥nt: Black Freshwater Pearl, White Freshwater Pearl, Amethyst, Rose Quartz, Aquamarine, Lapis Lazuli, Reflective Glass

Each piece is handmade, one of one.

Care note: metal — hand wash only, avoid submerging gem/pearl detail. Glass — hand wash, handle with care.

Alchemy of the Hand
Born of fire, cast in starlight.

Handmade, One-of-One

Every piece from M31 is designed and made by hand — precious metallurgy, soldering, and stone setting, worked one at a time from raw materials into something finished. Metal accessories are never mass-produced; each one is one-of-one and, once sold, gone for good. Laser cutting and 3D modeling round out the process for certain pieces and components — and will eventually bring harm reduction tools into larger-scale production, while the jewelry stays true to its one-of-one roots.

Materials
Pieces are built from silver, tin, stainless steel, crystal, pearls, acrylic and mixed findings, chosen with care for durability and safety — including a focus on harm reduction in the materiality of the ritual tools. Because each piece is handmade, slight variations in shape, texture, or stone are part of the piece, not a flaw.

Shipping
Domestic orders (including Puerto Rico) ship within 5–7 business days. Rush shipping is available for an extra charge. International shipping is available to Canada, the UK, Australia, New Zealand, Germany, the Netherlands, France, Sweden, and Ireland. Since every item is one-of-one, each piece is packed with individual care.

Returns & Exchanges
Because every piece is one-of-one, all sales are final. You're welcome to reach out anytime about damages, replacements, or resizing. Replacements for damage are handled case by case, and resizing or certain replacements may come at a cost — starting at the price of shipping the piece back to me, depending on the situation.

Custom Orders
Want something made just for you? Custom pieces start with a conversation — reach out with your vision, and a deposit secures your spot in the queue. Once confirmed, your piece is built one-of-one, just like everything else in the shop, and yours alone.

Founder Note
M31 started as my own path back to myself — reclaiming Cusmo, a decolonized word for my transness rooted in my Lache Colombian heritage, and turning the Catholic imagery I grew up with into symbols of spiritual self-respect instead of shame. Every piece I make carries that same intention: self-recognition, not perfection. And because access matters as much as beauty, M31 runs pay-what-you-can for trans people — no one should have to choose between rent and something that helps them feel like themselves.
