Quick answer

If you want to sample all textures at the best value, grab the UNI Variety Pack. If you already know you love bold steps, fine pyramids, or layered squares, buy the single UNI EMERALD, UNI DIAMOND, or UNI AMETHYST respectively.

Texture differences at a glance

The UNI Series offers three distinct internal textures, each designed to create a different sensation. The UNI EMERALD features large, horizontal step-like details that provide a bold, satisfying stimulation. The UNI DIAMOND uses finely spaced pyramid-like details for a delicate, teasing feel. The UNI AMETHYST employs layered square textures that create a gripping, enveloping sensation. There is no single "best" texture — the right choice depends on what kind of stimulation you prefer.

Cost per use: pack vs singles

Each UNI is a single-use disposable product, so cost per session matters. The UNI Variety Pack includes four units — EMERALD, DIAMOND, TOPAZ, and AMETHYST — for $22.07, which works out to about $5.52 per unit. Buying the singles separately costs $4.79 for EMERALD, $5.67 for DIAMOND, and $5.99 for AMETHYST. If you plan to try at least two different textures, the Variety Pack saves you money and gives you a fourth bonus texture (TOPAZ) to explore.

Trade-offs at a glance

  • UNI EMERALD (single): Bold step design for satisfying stimulation. Costs $4.79. Best value per unit among singles, but only one texture.
  • UNI DIAMOND (single): Fine pyramid design for intense stimulation. Costs $5.67. Delicate feel, but slightly pricier than EMERALD.
  • UNI AMETHYST (single): Layered square design for gripping, enveloping sensation. Costs $5.99. Most expensive single; unique texture not found in other singles.
  • UNI Variety Pack: Includes EMERALD, DIAMOND, TOPAZ, and AMETHYST for $22.07 ($5.52 per unit). Best value if you want to try multiple textures; includes a bonus TOPAZ not sold separately.

Product facts

  • UNI EMERALD: Bold Step Design for Satisfying Stimulation — large, horizontal step-like details. If you prefer pronounced, rhythmic sensations, the EMERALD delivers a more aggressive texture than the other two singles.

    UNI EMERALD

  • UNI DIAMOND: Fine Pyramid Design for Intense Stimulation — finely spaced pyramid-like details. The DIAMOND is ideal if you enjoy subtle, teasing sensations rather than bold ridges.

  • UNI AMETHYST: Layered square textures provide a gripping, enveloping sensation. The AMETHYST offers a unique "hugging" feel that neither the step nor pyramid designs provide.
