Product Information
Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.
Universal Bearing -
Dynamic and high static load performance
The Ronstan Universal Bearing incorporates our proven 2-stage bearing system
Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks.
Alloy cheek plates
Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.
Applications
Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 12m (40ft).
Various control line applications on larger yachts.
Alloy sheave models are available for use with wire.

Honestly I'm disappointed
Scent: Refreshing, Size: 16 Fl Oz (Pack of 1)
I had very high hopes for this body wash. This brand is well known, and a brand that I have loved for a couple years now. Nearly every Pur A'dor product I have ever tried, I have loved. Until this one. I expected a high quality, great smelling, skin softening body wash. What I got was something that smells very medicinal or chemical like. I did not, however, have any negative skin reactions to it, and it did leave my skin feeling adequately hydrated and soft. The scent though, is just not something I am able to enjoy at all. I have tried it several times, hoping the scent would grow on me, or somehow Improve, but it hasn't. At this point, I have put it to the side, and started using another product instead. I was thrilled to have caught a body wash by this brand on sale for $12, but I guess now I see why it was discounted so much. I'm not sure. This is not the norm for this brand at all. Hoping this is a one time fluke.

Fantastic!
Scent: Lavender, Size: 16 Fl Oz (Pack of 1)
I love this body wash. I have really bad allergies. I ordered other products recommended by doctors and even those still made my skin itch. This product is the only one that has not made me itch AND it smells FANTASTIC!

Such a pretty bottle and it feels so great on skin!
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I was so excited to try this serum, and honestly, it did not disappoint. What first caught my eye was the packaging—I’m a sucker for pretty bottles, and this one is stunning with its shimmery, rainbow-like colors. Even the serum itself has a subtle shimmer that matches the bottle, which I absolutely love.
The scent was the first thing I noticed. It has a light floral smell with a hint of honey, almost like a soft version of the old Sweet Pea scent from Bath & Body Works. It’s not overpowering at all. You only really smell it when dispensing or applying it—once it’s on your skin, the scent completely disappears. No headaches, no lingering fragrance.
Application-wise, this serum is silky smooth and spreads beautifully. It made me realize my skin wasn’t as soft as I thought—because after using this, my skin felt noticeably softer, hydrated, and plump. It absorbs well and leaves my skin feeling nourished without being greasy.
It does contain retinol, so the warnings about avoiding the eye area and limiting sun exposure are important. I’ll definitely be pairing this with a good hydrating sunscreen, especially during daytime use. I plan to ease into it by using it once or twice a week until my skin fully adjusts.
Overall, I love everything about this serum—the packaging, the light scent, the texture, and the results. My skin feels smooth, hydrated, and healthy. This is definitely a product I’m excited to keep using and would happily recommend.

The best serum!
Size: 1 Fl Oz (Pack of 1)
This is the best face serum, and the price is unbeatable. It makes my face feel silky smooth and hydrated for the whole day. I will not use anything else.
Plus, it smells good. Highly recommend!
