About Hardcore Begleri - Delrin Shells (single shells)

Hardcore Begleri - Delrin Shells

NOTE: This listing is for single shells only (not pairs), sold empty (no cores). Please add the components in the colours you want one by one.

Aroundsquare's Hardcore Gut System is a configurable system of interchangeable weighted cores and exterior bead shells, which lets players build ideal setup by mixing and matching components. The Hardcore system was first launched in 2017, and has expanded over the years to include a wealth of options for players.

The delrin shells have become the preferred beads of many players, due to their vibrant colours, durability, and distinctive (loud) clack. Delrin is a durable material, with a warm and comfortable feel. Although it is technically a plastic, it feels more like wood to the touch, and is extremely durable. Although it is possible to crack these shells over time, it is extremely uncommon, and they should hold up to extended use. The material cannot be injection moulded, and these shells have been precision machined--just like their metal counterparts.

The delrin shells are too light to play well on their own, and need to be paired with hardcore gut beads (sold separately) for best results. They are available in four designs, and six colours each.

Details:

Delrin Titan shells: 3.5mm top bore; 4.3g each (empty); 20 by 20mm
Delrin Everyman shells: 3.5mm top bore; 3.1g each (empty); 17 by 17mm
Delrin Standard shells: 4mm top bore; 2.5g each (empty); 16mm by 16mm
Delrin Boss shells: 3.5mm top bore; 4.6g each (empty); 21mm diameter

Please note that items included in the package (strings, stickers, patches, bags etc.) vary in colour and quantity depending on availability, and may not be exactly as shown in the photos.
