Ucap Core Module – Single & Dual

Price range: $39.99 through $79.99

The Ucap Core Module bridges structure and evolution — from flat to inverted, from classic to extended.

Description

The Ucap Core Module – Single & Dual redefines modular precision within the chastity system.

Compatible with CC11, CC12, CC16, CC18, CCK1031, CCK1041, CCK1017, and CCS1089, it allows seamless transformation between flat and inverted configurations — expanding the possibilities of structure, control, and exploration.

The Single Core represents the most classic version — clean, balanced, and true to the original design philosophy of Ucap.

The Dual Core, launched in late 2025 after ongoing user feedback, introduces a longer, more stable form that enhances both depth and comfort. It can also be detached and used as a Single Core when desired, maintaining full flexibility in one refined system.

Each piece is crafted from polished stainless steel and carefully hand-finished, merging mechanical precision with tactile clarity.

A modular component born from feedback, refined through play — for those who seek to perfect the art of restraint.
