Lone Star’s plastic names follow the phonetic alphabet, and several of them are easy to misread as versions. Alpha is the firm baseline, Bravo the gummy one. Delta is the mid-tier, and Delta 2 is a separate stiffer plastic, not a second version. V1 and V2 are Victor 1 and Victor 2, two soft premium blends that float, not mould revisions.
Lima is the lightweight blend, Charlie the translucent one kept for special editions, and Founder’s is a real metal-flake plastic that only appears on Tour Series stamps.
