Crystal Jellies 18 Inch Double — Crystal Jellies Double Dong by Doc Johnson

Crystal Jellies 18 Inch Double User Guide & Play Styles

Dual penetration play for couples exploring together

The crystal jellies 18 inch double dong is designed with dual penetration in mind — each partner takes one end, and the flexible shaft adapts to whatever position feels most comfortable. The large-size format means there’s plenty of length to share, and the soft body-safe material keeps sensation smooth and intimate. A small amount of water-based lubricant enhances the experience on both ends. For more ideas on building intimacy around toys like this, explore our Couples Pleasure pillar guide.

Solo and strap-on harness use

The Doc Johnson double-ended dong works just as well for solo penetration play — the 17.5-inch insertable length gives full control over depth and angle. It’s also compatible with most strap-on harnesses, making it a versatile pick for the double penetration category. After play, rinse with warm water and a dedicated toy cleaner to keep the phthalate-free surface in great condition — simple care that extends the life of any personal pleasure device.
