Safety-First Design Tapered tip for easy insertion, narrow neck for comfort, and a mandatory flared base to prevent full entry and ensure safe removal.

Ergonomic Sizing Beginner-friendly (2–3 cm diameter, 8–10 cm length) to advanced sizes; some curved for comfort or indirect stimulation.

Body-Safe Materials Medical-grade silicone (non-porous, hypoallergenic), ABS plastic, or glass/metal for temperature play. All phthalate-free and CE/RoHS compliant.

Smooth, Seamless Surface No ridges or seams to reduce friction and prevent irritation.

Functionality Options Non-vibrating (shape-based) or vibrating (quiet, multi-mode). Some feature O-rings for strapon use—always with sealed electronics and flared base.

Easy Maintenance Silicone/glass/metal: washable, boilable, toy-cleaner safe. TPE: hand-wash only; avoid silicone lubes.

Lubricant Required Anus lacks natural lubrication—use water-based lube. Avoid silicone-based lubes with silicone toys.
