These loops are the refill bands for the Callicrate Smart Bander, a ratcheting tool used to perform bloodless castration on livestock. Each loop is molded from a specialty latex compound engineered to hold high tension without stretching out or slipping once applied. A patented no-slip clip locks onto the band as the bander is ratcheted, so the tool sets the tension rather than the operator guessing at tightness, giving every animal a fit sized to its own anatomy. The loop surface carries a light lubrication that helps it glide evenly around tissue and reduces friction and abrasion during placement. Beyond castration, the same loops can be used with the bander for horn removal, tail docking, and treatment of certain prolapse cases. Loops are sold as a refill pack only; the bander tool and cutter are purchased separately. Bags are packed in bulk counts so a supply of bands is on hand for repeated use across a herd or flock.
