Cords Club Review: Titanium Flat Back Earrings, Gauge and Post Lengths, Prices and Returns
Cords Club is an online jewelry shop built around flat back stud earrings: threadless push-pin studs with a flat disc on the back, designed to sit flush behind the ear. It also sells clicker hoops, hoop charms, daith and cartilage hoops, necklaces, bracelets, earring organizers and monthly stud subscriptions. Most single flat back studs cost $15 to $56, with a typical price around $25, and the core pieces are made of ASTM F136 implant-grade titanium.
Despite the name, Cords Club is a jewelry brand, not a shoelace or cord store. This review covers what it sells, the gauge and post-length details you need to check, prices, shipping, a 30-day return policy with a 4% refund fee, and the 365-day warranty.
At a glance Checked October 2026
Cords Club suits people with sensitive ears or multiple piercings who want comfortable, mix-and-match studs and hoops. Product pages list gauge, post length, disc size, design size and materials, which makes it easier to buy for a specific piercing. Watch the fees: refunds carry a 4% processing fee, worn flat backs are not resold for hygiene reasons, and free returns depend on optional order protection.
- Best for: Lobe, helix, flat and cartilage piercings, sleeping in earrings, sensitive ears and building an "ear stack."
- Typical price: single flat back studs $15–$56 (most about $25); pairs about 10% less than two singles; hoops $10–$66; charms $7–$22.
- Shipping: free on US orders over $75; processing 1 to 4 business days; ships internationally with duties collected at checkout.
- Returns: 30 days from the order date, unworn and in original packaging; refunds minus a 4% processing fee.
- Watch out for: Studs are sold singly unless you pick a pair, and lost flat backs are not covered by the warranty.
What Cords Club sells
The store's product feed showed more than 750 listings when we checked, and the first 750 broke down roughly like this:
- Flat back studs (about 350): cubic zirconia, enamel, pearl-style and novelty designs, including seasonal and themed collections.
- Hoops (about 120): no-poke clicker huggies in several diameters, many with fixed charms.
- Charms (about 100) that hang from compatible hoops, plus necklace charms.
- Clicker hoops for daith, septum and cartilage in 16 gauge.
- Necklaces and bracelets in stainless steel or gold PVD-plated steel.
- Accessories: replacement and decorative flat back posts in several lengths, a flat back applicator ($16), travel palettes ($16) and pouches ($12).
- Subscriptions: Studs of the Month and a kids' Cutie Club box, each $30 a month for a pair of unreleased studs with US shipping included.
There is a Cords Club for Kids collection with colorful enamel studs, and the Cutie Club listing says its designs are phthalate-free and tested safe for children.
Gauge, post length and materials
Flat backs only work if the post fits your piercing, so these details matter more than with ordinary butterfly-back earrings. From the FAQ and product pages:
- Standard flat back: 18 gauge (1mm) post, 6mm (1/4 inch) long, with a 4mm back disc, unless the listing says otherwise. The brand says its fronts are compatible with most 16 or 20 gauge threadless labret posts.
- Other lengths: replacement posts are sold separately in 5mm to 10mm lengths, at $9 to $11 each, for thicker lobes, cartilage or swelling.
- Hoops: most huggies are 20 gauge (0.8mm) with interior diameters listed per item, such as about 10mm or 12mm. Daith and cartilage clickers are 16 gauge in 8mm or 10mm.
- Design size: each listing gives the approximate size of the front, for example 2 x 4.8mm for the Baguette stud, and the brand asks you to check your own ear placement before ordering.
- Materials: studs and many hoops are ASTM F136 implant-grade titanium, either polished or with 18K gold PVD plating. Charms are 316L surgical steel; necklaces and some hoops are stainless steel, and on the Mixed Metal Essential Hoops the post is unplated stainless steel.
The brand describes titanium as its most hypoallergenic option and says fewer than 1% of people are allergic to it. That is the brand's claim; if you have a known metal allergy, choose the titanium options and check each listing's materials, because chains and charms are steel. The FAQ says about 99% of its earrings are waterproof, with exceptions such as some hand-painted styles, and product pages say rinse after salt water, chlorine or lotions.
Flat backs hold by tension between the pin and the post. The FAQ says to check and adjust the tension each time you wear them, and clicker hoops come with a fit tip to adjust the post until it clicks. Insertion takes practice, and the brand recommends its titanium applicator and links video demos.
Prices
Prices are in US dollars. Flat back studs are sold individually; choosing a pair in the variant menu saves 10%. Across about 350 stud listings, single prices ran from $15 to $56 with a middle price of $25. Examples at the time of writing:
- Baguette Flat Back Stud: $25 single, $45 pair
- Brooch Flat Back Stud: $25 to $32 single depending on finish
- Coffee Titanium Celestial Hoops: $43 pair
- Mixed Metal Essential Hoops: $49 pair
- Fluted Halo Daith Hoop: $42 to $44 single
- Hoop charms: $7 to $22 each (sold singly)
- Necklaces: $18 to $74; bracelets $22 to $44
- Themed flat back bundles: $90 to $128
Because studs and charms are priced per piece, compare the pair price when you add to cart. Bundle prices say they do not combine with other discounts.
Shipping
- Free shipping: on qualifying US orders over $75. Standard rates below that were not listed on the policy page and appear at checkout.
- Processing: typically 1 to 4 business days, Monday to Friday, longer around launches and holidays. No weekend or US postal holiday shipping.
- International: the brand says it ships to most locations, with duties and taxes calculated and collected at checkout.
- Lost or stolen packages: covered for US orders only if you bought order protection at checkout; otherwise the brand says it is not responsible once the carrier has the package.
Returns and warranty
- Window: return or exchange within 30 days of placing the order, started through the online portal. Packages sent without a portal request are not accepted.
- Condition: perfect condition, unworn and unused, in all original packaging. Worn flat back studs are not resold for hygiene reasons.
- Fees: refunds carry a 4% processing fee (waived for international returns); shipping charges are not refunded. With order protection, US exchanges and store credit have no return shipping fees; without it, the label cost is deducted from your refund.

- Refund timing: within 10 business days of approval.
The 365-day warranty covers pieces that break from a manufacturing issue within a year of purchase, with a replacement or shop credit of equal value. Claims need photos and the order number. It does not cover lost items, flat backs lost through tension problems, damage from force, or normal plating wear and fading. Wrong or missing items must be reported within 7 days of delivery.
Who should buy from Cords Club
- People with sensitive ears who want implant-grade titanium studs and hoops and can check materials per listing.
- Anyone who sleeps in earrings or wants studs that will not poke behind the ear.
- Ear-stack builders who like mixing single studs, hoops and charms across several piercings.
- Parents looking for colorful kids' studs or a monthly subscription gift.
