[COMING SOON] KYO Storage Sack

How you store your gear matters just as much as how you clean it. Storing freshly powdered TPE in cardboard boxes or sealed plastic bags can permanently ruin the material over time. The KYO Breathable Storage Sack provides a lint-free, dust-tight shield engineered specifically to maintain optimal TPE health between sessions.

• Anti-Leaching Defense: Prevents dry cardboard or porous wood from drawing out essential mineral oils and plasticizers from your TPE.
• Micro-Breathable Fabric: Allows residual microscopic moisture to evaporate naturally, preventing internal condensation, mold, and sour odors.
• 100% Lint & Fiber-Free: Unlike standard cotton pillowcases or bath towels, the ultra-fine weave leaves zero abrasive threads on sticky or powdered surfaces.
• Discreet Blackout Styling: Features a clean, unbranded exterior with a dual-drawstring cinch for private bedroom or closet storage.

The Two Big Storage Traps

Trap 1: The Original Cardboard Box

Many collectors store their sleeves directly inside the retail cardboard box. Over time, raw cardboard acts like a sponge for mineral oils. It slowly leaches the plasticizers out of the TPE, leaving your sleeve stiff, brittle, and prone to tearing along stress points.

Trap 2: Sealed Plastic Bags (Ziplocs)

Airtight plastic bags trap even the smallest trace of humidity. In a dark closet, trapped moisture combined with body warmth creates the ultimate breeding ground for black mold and mildew, permanently destroying the hygienic seal of the toy.

The Solution: The KYO Storage Sack strikes the perfect balance. It is dense enough to block dust, pet hair, and sunlight, but breathable enough to ensure the internal environment remains bone-dry and fresh.

Choose Your Format

Small Format (11.8" x 5.9" / 30cm x 15cm)

The standard size for compact and medium handheld onaholes (diameter under 5.9 inches). Perfect for models like the ToysHeart R-20 series, Tamashii No Ai sleeves, and compact travel units.

Large Format (19.7" x 19.7" / 50cm x 50cm)

An oversized square footprint engineered for substantial hardware. Accommodates full-scale onahips, half-bodies, and torsos with a circumference up to 39 inches (100cm). Easily fits models like the Ereshkigal Cherry 6.1kg, Cherry Hyper 8kg, and the Auto SPD-X.

*Pro-Tip for Large Hips: If you use the original molded styrofoam cradle to support the weight of your hip, place the hip inside this breathable sack first before setting it in the cradle. This prevents the TPE from chemically reacting with or sticking to the foam.
