КАЧЕСТВО MANIAK, И ЕДНА ФАНТАСТИЧНА ДИЗАЙН. ЗДРАВА/УСТОЙЧИВА (note: original says RESISTENTE meaning sturdy; in Bulgarian "издръжлив" might fit better). Provide direct translation: "КАЧЕСТВО MANIAK, И ЕДНА ФАНТАСТИЧНА ДИЗАЙН." "RESISTENTE" translates to "ИЗДРЪЖЛИВА". So final:
КАЧЕСТВО MANIAK, И ЕДНА ФАНТАСТИЧНА ДИЗАЙН. ИЗДРЪЖЛИВА
But grammar: "Едно фантастично дизаин" Bulgarian "фантастичен дизайн" feminine noun "дизайн" is masculine in Bulgarian "дизайн" is masculine; adjective agrees: "фантастичен дизайн". So:
"КАЧЕСТВО MANIAK, И ФАНТАСТИЧЕН ДИЗАЙН." plus "ИЗДРЪЖЛИВА" would modify what? "RESISTENTE" standalone adjective; no subject. In Spanish it's "RESISTENTE" meaning "durable" as attribute of product. In Bulgarian maybe "ЗДРАВ/ИЗДРЪЖЛИВ" but single word "ИЗДРЪЖЛИВ" matches.
So final line: "КАЧЕСТВО MANIAK, И ФАНТАСТИЧЕН ДИЗАЙН. ИЗДРЪЖЛИВА" The last word mismatched gender; maybe keep as standalone: "ИЗДРЪЖЛИВА" is feminine; would pair with "исдреживa"? Better to use "ИЗДРЪЖЛИВО" (neuter adverbial?) not good. In Bulgarian adjectives in short form after dash. Safer: "ИЗДРЪЖЛИВА" as a predicate. We'll output:
КАЧЕСТВО MANIAK, И ФАНТАСТИЧЕН ДИЗАЙН. ИЗДРЪЖЛИВА
Let's provide exactly as a single text line without extra commentary.
