Frontier Japan Summer secrets next

Frontier Japan Summer Secrets Next is the follow-up in Frontier Japan's Summer Secrets line. The non-penetrating sleeve is built around a narrow entrance and a crunchy, large-ridge internal sculpt — the inner walls carry deeper-than-average ribs that produce a clearly granular sensation rather than a smooth one. The material is single-layer soft Japanese TPE.

• Non-penetrating closed-end construction
• Narrow entrance with large internal ridges
• Soft single-layer Japanese TPE
• Mini lotion included
• Made in Japan by Frontier Japan

Practical note: the prominent rib geometry rewards slower strokes — they read more clearly than fast motion. Apply lotion at both the entrance and along the length on first use; the large ridges hold lubricant well between strokes. Rinse with lukewarm water after use, air dry, and powder lightly before storage to preserve the surface. Shipped from our Tokyo warehouse with DDP all-inclusive delivery — shipping and duties to your country are included in the listed price.
