Crowned Jewels Upminster is a great lightweight aluminum butt plug designed for maximum ergonomics and extended use.
Aluminum butt plugs share a lot of the same benefits of steel – they’re very firm and great for heating up or cooling down for extra sensation. The Crowned Jewels’ Upminster aluminum is much lighter than stainless steel toys like the nJoy Pure Plug, if that’s what you prefer.

Lighter Than Steel, but Still Solid
The main differentiating factor for the Crowned Jewels Upminster butt plugs is that they are made of high quality polished aluminum (or even anodized titanium). Like stainless steel, aluminum is completely nonporous, antibacterial, and body-safe. However unlike stainless steel, aluminum is quite light.
The toys still feel just as solid as other metal toys, but they weight is closer to silicone toys. The plugs come in 3 basic sizes:

The other unique thing about the Upminster butt plugs is the curved, tapered neck (rather than straight cylindrical necks on similar metal plugs).
This means these plugs sit very naturally once inserted, and are quite comfortable despite being made of hard metal. The Upminster also has a soft silicone ring that acts as the flared base. It is a little wide due to the circular shape, but the soft material means it still sits comfortably.
You have to give it to Crowned Jewels for their presentation and shipping – all their toys come in a luxurious velvet pouch and classy wax-sealed tube. It really gives a luxurious feel to the whole experience, and gives you a way to keep your new toy safe for years to come.
Lastly, for a hefty price jump you can get the Upminster in anodized titanium. These plugs are functionally similar to the cheaper aluminum, however the anodization process gives beautiful colors like gold, or iridescent blue/purple, while still being completely body-safe.
Extremely Comfortable for Extended Wear
Like other metal butt plugs, the Crowned Jewels Upminster is a fantastic choice for long term and/or daily wear. Metal toys can be used with silicone lube, which is ideal for extended wear because it doesn’t dry out like water-based lube.
The design of the butt plug is also very ergonomic, with the curved neck and soft, flexible base. The fact that aluminum is lighter than steel is the make-or-break factor for this toy. If the steel toys like the nJoy Pure Plug are too heavy for you, then an aluminum butt plug is the perfect choice for you. We like that steel plugs have extra weight to them, but different strokes for different folks.
As a standalone anal toy for use in the bedroom it’s a fine butt plug, and the smooth curves are great for warming up for bigger anal things.
The Crowned Jewels Upminster butt plugs are a great alternative to a market filled with stainless steel toys. The aluminum does provide some unique characteristics vs steel or silicone, and the plugs are excellently designed in a lot of ways. If cost isn’t a factor, the anodized titanium butt plugs are some of best, and most unique-looking toys we’ve ever seen.
