## Prepare a cart (platform instructions)

Only when the user asks to buy: select a purchasable variant above. Do not create carts for catalog reading or indexing.

API contract: https://www.onaholestation.com/agent-read-openapi.yaml
POST https://www.onaholestation.com/api/agent/checkout-sessions
No authentication is required. Headers: Content-Type: application/json; Idempotency-Key: a unique 8-128 character request key (reuse only for an identical retry).
Replace the placeholder with the user-selected variant_id; quantity must be 1-5, up to 10 distinct items. Request body:
```json
{"country":"ca","locale":"en-CA","items":[{"variant_id":"variant_REPLACE_WITH_USER_SELECTED_VARIANT","quantity":1}]}
```
On success, return checkout_url to the user. The link expires after 48 hours and does not reserve prices or stock. The user must open it, review and confirm the cart, and complete payment. The same authorized browser can resume an adopted cart for up to 7 days from preparation; an expired unclaimed link needs renewed user purchase intent before a new operation, never automatic cart creation. Agents must not submit orders or payment data.
Retry the same key and body after transient failures or request_in_progress. If checkout_result_unknown is returned, stop automatic retries and ask the user to verify; never switch to a new key. Duplicate prevention depends on retained operation state for up to 7 days; Redis data loss or eviction can remove this protection.
If user authorization is enabled, shipping_preference_token may reference a saved default address explicitly authorized by the user. Do not send a raw address. Keep preference/status tokens private and out of URLs. A returned status token requires separate user consent on the handoff page before read-only status access; address/status grants never authorize order submission or payment.

## Summary

> Complete 4-in-1 care for your onahole—warming, cleaning, drying, and preserving. Boost longevity and hygiene with this all-in-one essential kit\!

## Description

> An onahole is only as good as its upkeep. Body oils, leftover lotion, and trapped moisture silently eat away at soft TPE — the tunnel turns sticky, odors build, and a toy that should last for years starts feeling tired within months. The A-ONE Onahole Care 4-in-1 Maintenance & Warming Support Set bundles the four tools Japanese owners actually reach for into one box: warm it, clean it, dry it, preserve it.
> 
> What's in the box
> 
> USB warming stick (39 g) — brings the tunnel up to near body temperature in about 5 minutes, for a far more realistic first touch.
> 
> Sponge cleaning stick (2 g) — a slim swab that reaches deep into textured tunnels to lift hidden lotion residue.
> 
> DRY moisture-absorbing stick (27 g) — wicks water out of the channel after washing, preventing mold and odor.
> 
> Silver-ion hole preservation powder (10 g) — antibacterial, deodorizing finish that keeps the surface smooth and extends the toy's life.
> 
> Why warming changes everything
> 
> Cold TPE is the number-one realism killer. Owners who pre-warm consistently report the material feeling softer and the texture reading clearer — and a dedicated warmer and dry-stick combo is the standard fix. A-ONE's stick runs off any USB port; never leave it heating much past 15–20 minutes, and pair it with lotion for easier insertion. Finish the routine with the dry stick and powder: wash, dry, dust, store. Stock the rest of our onahole care accessories and browse more A-ONE products to keep your whole collection rotation-ready.

## FAQ

### What exactly comes in the A-ONE 4-in-1 Onahole Care Set?

> Four items: a USB warming stick (39 g), a sponge cleaning stick (2 g), a DRY moisture-absorbing stick (27 g), and 10 g of silver-ion hole preservation powder. Together they cover warming, cleaning, drying, and preserving.

### How long does the USB warmer take to heat an onahole?

> About 5 minutes to reach near body temperature. Reviewers recommend not leaving warmers in much longer than 15–20 minutes; newer temperature-control models stop heating automatically once they hit their target.

### Will the dry stick fit narrow or heavily textured tunnels?

> The slim stick fits most standard tunnels and absorbs residual water that towels can't reach. Handle it gently — absorbent sticks can be brittle — and go slow with very narrow entries to avoid stressing the material.

### What does the silver-ion powder do?

> It adds an antibacterial, deodorizing finish after cleaning, keeps the surface smooth instead of tacky, and extends the toy's lifespan. Apply it only to a fully washed and dried toy.

### This set is currently out of stock — what's the alternative?

> Try the standalone warmer-and-dry-stick combo or individual care accessories in our accessory collection, and check back — A-ONE care kits restock regularly.
