My Verdict

I think that the Master Series Locking Bracelet & Key Necklace set is a really cute and sexy idea. Both items are cute and sleek. This set is a perfect balance between discrete and kinky, and I could easily wear it in public because it perfectly blends with my jewelry. I think it is a gentler alternative to chokers or other day collars. But I have to point out that the bracelet is tiny, and even though it fits me nicely, I am sure not many people will be able to wear it, especially because it doesn't have any adjustable features.

Buy, if you...

  1. enjoy wearing kinky jewellery
  2. want an alternative to a day collar
  3. want a spicy set of jewellery for you and your partner

Don't buy, if you...

  1. have wide wrists
  2. prefer adjustable bracelets
  3. prefer something more discreet

Personal Experience

My Personal Experiences with Master Series Locking Bracelet & Key Necklace

I love jewelry, and if I can find something that’s both pretty and kinky, I want to have it! And since this set is made for 2 people to wear, I thought it’d be a great way to add some spice and sparkle to our date nights. And it definitely did! I think the bracelet is really cute, and I was surprised to see that it’s actually so well-designed and executed. It’s lightweight, thin, and blends nicely with my other silver bracelets. When it comes to the necklace, I think it looks nice. I like how discreet it is, especially because my partner doesn’t wear any jewelry, so giving him a kinky piece of jewelry to wear in public could’ve been hard. But the key is so small and simple, you can easily wear it under the shirt without anyone noticing.

The Good and the Bad

Overall, both pieces are well-made, although I feel like there was more thought and attention put into the bracelet than the necklace. I just spotted some color imperfections around the key, and it’s just not as smooth and shiny as the bracelet. When it comes to the lock, I think it works well, it kind of reminds me of those diaries with a lock that I used to have as a kid. The Mater Series is much more durable than that, but the vibe is similar. But the biggest issue I see is the size of this bracelet. It is TINY! It fits me nicely, but it’s non-adjustable and really small, so if you have wider wrists than me, there is nothing you can do.


Master Series Locking Bracelet & Key Necklace Design

The locking bracelet and the necklace are made of shiny and sleek metal. The bracelet looks cute and quite innocent; it’s thin and has a heart-shaped lock and 2 sparkly gems for added charm. But I was surprised to see how tiny this bracelet is. I had no problem closing it on my wrist, but I think it won’t fit many people. The necklace design is really simple and discreet.

Ease of Use

Master Series Locking Bracelet & Key Necklace Ease of Use

The bracelet has a simple snap design, so it’s quick and easy to close, and it’s much easier than usual chain-like bracelets. On the other hand, it doesn’t have any adjustable features, so if you have wider wrists, that’s just not going to fit at all. Opening it with the key goes pretty smoothly, although it’s important to note that you can only open the bracelet with the key, which is a cool feature for a couple’s play; however, if you happen to lose the necklace, you might be in trouble!


Master Series Locking Bracelet & Key Necklace Quality

Both the bracelet and the necklace are made of metal, so they are sleek and durable. In my opinion, the bracelet looks much better than the necklace. It has much more detail, and the sparkly gems add a bit of charm, but the necklace looks very simple.


Master Series Locking Bracelet & Key Necklace Price

I haven’t seen many locking bracelets with a key necklace on the market, so it’s hard for me to compare the prices, but I think for such a unique and pretty accessory, the price is great. I would recommend getting it as a gift for your sub, although I would probably change the packaging for something cuter.


Master Series Locking Bracelet & Key Necklace Performance

Wearing this locking bracelet feels like wearing any other jewelry; it’s a bit thicker and heavier than something I would usually go for, but I enjoyed wearing it. I really like the design, it’s a nice balance between kinky and cute, so you can easily wear it in public, especially if you pair it with other bracelets. Opening it and closing is quick and easy as well, I had no problem with that.


Master Series Locking Bracelet & Key Necklace Packaging

The packaging was a bit disappointing, to be honest. The locking set came in simple plastic packaging with Mater Series branding on it, which definitely took away the fancy and sexy experience I was hoping for. I understand that the Mater Series is known for making kinky accessories, but they could step it up with jewelry pieces.

Materials and care

Master Series Locking Bracelet & Key Necklace Materials and care

The bracelet and necklace are made of metal, so they have that sleek and shiny look. I would say that the bracelet is durable and the lock is sturdy, so you will be able to use it for a long time. When it comes to cleaning, you can just polish it with a dry cloth, and when it loses its shine, you can clean it like any other metal jewelry (baking soda paste should do the trick).
