Rookie card of Kon Knueppel in a space/planetary-themed Topps Chrome insert design; shows the RC logo on the front and a vivid rainbow chrome finish indicating a refractor parallel. The back copy references his 2024/25 three-point percentage and the card code PPS-10 is printed on the back. Produced by Topps (copyright 2026) and clearly an insert/refractor rather than a standard base card.
