The Tantus Curve Soft in Sapphire is a curved, stepped silicone dildo with a wide flared base for solo or compatible harness use. The Stag Standard SKU is NAL-85259, the supplier item is 85259, and Tantus identifies the Sapphire variant as maker SKU 0119-66-TC with GTIN 019213853655.
Catalog correction: Tantus’s current first-party variant record and the exact supplier package image identify this SKU as Curve Soft / Super Soft in Sapphire. The prior “Medium-Firm” wording came from a conflicting supplier title and is not used as a verified product fact.

The dimensions above are published manufacturer or supplier specifications, not measurements taken by The Stag Standard and not a fit guarantee. The supplier’s older 4.25-inch circumference entry does not mathematically align with the current 1.5-inch diameter, so the circumference is intentionally omitted.
Choose the size and prepare
Compare the 1.5-inch listed diameter, curved shape, and stepped ridges with a product you already use comfortably. Softness can change how a toy bends, but it does not replace size or fit checks. Start slowly with plenty of compatible lubricant and never force insertion. Avoid numbing products because they can make it harder to notice pain or injury. Stop for sharp or increasing pain, numbness, bleeding, unusual swelling, or resistance that does not ease.
For anal use, keep the flared base completely outside the body and accessible throughout use. A flared base reduces retrieval risk only when it remains wider than the widest inserted section and cannot enter the body; it is not a guarantee of suitability for every body or position.
Harness and partner use
“Harness compatible” does not mean every harness will fit. Compare the shaft and base with the harness maker’s O-ring opening, base-shape, and retention requirements. Secure the base and test that it remains seated before body contact. With a partner, agree on pace, depth, and a clear stop signal before beginning and keep communication active.
Cleaning, sharing, inspection, and storage
Tantus currently lists Curve Soft as boilable and dishwasher safe, while the exact Nalpac record specifies the top rack. Follow the current package and manufacturer directions before using high heat, remove lubricant and other residue, and dry the product completely before storage. Water-based lubricant is the conservative default; follow Tantus’s guidance and spot-test before using another formula.
Inspect the shaft and base before and after use for tears, cracks, tackiness, discoloration, persistent odor, or other damage. Do not use a damaged product. If sharing, or when moving between body areas, use a fresh compatible barrier and clean the product between people or uses. Store it separately in a clean, cool, dry place.
