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.

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.

finally organized all my jewerly!
Color: Black
This jewelry box completely transformed the way I store and access my accessories. It’s not just functional, it’s genuinely beautiful, with a sleek design that looks great on my dresser. The exterior feels sturdy and well-made, and the interior is soft and luxurious, keeping all my pieces protected and tangle-free.
There’s a perfect place for everything: rings, earrings, necklaces, and even watches or bracelets. I especially love the multiple compartments and drawers, which make it easy to separate everyday items from special pieces. No more digging around or untangling chains!
The mirror inside is a thoughtful touch, and the box itself feels compact enough for smaller spaces while still holding a surprising amount. It’s one of those things that makes daily routines feel a little more put-together.
If you’re looking for a jewelry box that’s practical, elegant, and gift-worthy, this one checks every box. Great for personal use or as a thoughtful present.

Prefect Travel Case
Color: Black, Color: Black
I got this for taking my jewelry on the go. I have to say that I was pleasantly surprised by the quality it feels very sturdy. It has several spots to hold jewelry and keep it organized. The outside is textured and it closes with a snap which can be done easily.
