The wrist and ankle cuffs feature adjustable buckles and generous padding, making them inclusive for various body types and ensuring a snug, secure fit for both partners. Care & Safety Cleaning Instructions: Wipe the nylon straps and cuffs with a damp cloth and mild soap. The silicone butt plug and bullet should be cleaned before and after every use with warm water and a dedicated anti-bacterial toy cleaner. Compatibility: Use only water-based lubricants with the silicone butt plug and bullet. Silicone-based or oil-based lubricants will degrade the material of the toys and the linings of the cuffs. Safety Notes: Always establish a "safe word" before beginning restraint play. Ensure the person in restraints is never left unattended. Do not over-tighten cuffs; check for proper circulation frequently. Storage: Store in a cool, dry place away from direct sunlight and separate from other toys to prevent material transfer.

Yes. The SEI MIO Complete Surrender is an ideal "entryway" kit because it is non-permanent and includes soft-lined restraints. It allows couples to experiment with bondage safely without investing in heavy hardware or permanent bedroom modifications. Will the under-mattress straps damage my bed? No. The straps are made of soft but durable nylon webbing designed to slip between the mattress and the box spring or bed frame. They do not require screws or adhesive, leaving your furniture completely unmarked. What kind of lubricant should I use with the butt plug? You should only use high-quality water-based lubricants. Avoid silicone-based lubes, as the butt plug is made of body-safe silicone which can be "melted" or pitted by silicone-heavy formulas. How do I use the play dice in a scene? The dice are designed to take the guesswork out of your play. Roll them to determine the next "action" or "location" for a touch. It's a great way to build tension and introduce variety when you aren't sure what to do next while your partner is restrained.
