Cajas de CS2: ¿Qué Cajas Abrir en 2026 (Mejor ROI)?
Engaging in CS2 case openings is akin to gambling – let’s be upfront about this. However, some cases offer superior potential returns compared to others. Here’s the 2026 analysis.
The Reality of Case Opening
Note: Opening cases typically results in negative expected value. On average, players tend to lose money. If you’re after specific skins, acquiring them directly from our marketplace is usually a more economical option.
Nonetheless, here’s what you should be aware of if you decide to open cases.

👉 Budget Gloves Guide – Consider buying gloves directly instead!
Cajas You Should Avoid
- High-priced cases (€10+) – Bravo, eSports cases – Not justified by the cost
- Older operation cases – Contain low-value items, yet are pricey
- Cajas with depreciated items – Always verify item prices beforehand
The Math Behind Case Opening
| Raroza | Odds | Average Pulls Required |
|---|---|---|
| Azul (Mil-Spec) | 79.92% | 1 |
| Púrpura (Restringido) | 15.98% | 6 |
| Rosa (Clasificado) | 3.2% | 31 |
| Rojo (Covert) | 0.64% | 156 |
| Oro (Knife/Gloves) | 0.26% | 385 |
At approximately ~€2.50 per opening (case + key), you’d spend around ~€960 on average to obtain a knife. Most knives tend to be valued lower than that.
