Meet the Rear Assets Trainer Kit - Multicolour - Rainbow Heart - Multi Coloured Metallic Butt Plugs with Rainbow Hearts - Set of 3 Sizes, your bright, shiny invitation to explore gradually, confidently, and with a wink. This kit is all about choice and progress. You get three plugs in graduated sizes, so whether you’re brand new to this style of play or just love a step-by-step warm-up, you can pick the piece that matches your mood and comfort level right now.
Let’s talk vibe first. These plugs are made from aluminium with a metallic, chrome-plated look that catches the light in the most playful way. The multicolour finish gives each piece a fun, rainbow glow, and the heart-shaped gem at the base adds a sweet little sparkle. It’s cute, it’s cheeky, and it feels like a tiny celebration every time you reach for one. Who said training can’t be pretty?
The magic of a trainer kit is in the options. You’re not locked into one size or one style of session. The small plug measures 7.01 cm long and 3.20 cm wide, making it a friendly starting point for gentle exploration. The medium steps things up to 8.21 cm long and 3.41 cm wide, giving you a slightly fuller feel when you’re ready. And the large finishes the trio at 9.30 cm long and 4.09 cm wide for those moments you want something more substantial. It’s like having a little rainbow ladder of confidence, one heart at a time.
Design-wise, the shape is smooth and tapered, helping you ease in without fuss. The firm aluminium build provides a solid, steady sensation that many people love for its crisp, clean feel. And because each size is distinct but still in the same comfy style family, moving from one to the next feels natural rather than daunting. Whether you’re practising solo, pairing it with other play, or letting a partner choose your next level, the set gives you room to experiment without pressure.
Another handy perk: these plugs are suitable with all lubricants. So if you’ve already got a favourite, you’re good to go. If you’re still figuring out what you like, this kit lets you try different textures and find your perfect match. A good glide makes everything smoother, comfier, and more enjoyable — especially when you’re working through sizes.
For best results, slow is the secret sauce. Start with the smallest size, add plenty of lube, and take your time warming up. Let your body lead the pace and enjoy the build-up. After play, wash each plug with warm water and toy cleaner, dry thoroughly, and store somewhere clean so they stay shiny, safe, and ready for next time.
If you’re looking for a playful, confidence-building way to explore with a bit of sparkle, this rainbow trio is a gorgeous place to start. So go on then — which heart is getting the first date?
