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

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:

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

> G Project Hole Clean Brush: Simplify cleaning and maintain your masturbator effortlessly\!

## Description

> The G Project Hole Clean Brush is the tool Japanese onahole care is built around: a slim 247mm wand with soft, fan-shaped bristles engineered to scrub deep inside non-penetrating tunnels where fingers and rinse water alone cannot reach. Ordinary bottle brushes are too stiff and gradually scratch TPE; this brush is designed specifically for delicate onahole materials, lifting out residue without tearing the texture.
> Why your collection needs one
> 247mm full-length reach — scrubs the far end of long tunnels and hip or torso-style toys
> Soft fan-shaped bristles — clean textured interior walls with zero abrasion
> TPE and silicone safe — made for the materials onaholes are actually built from
> Extends toy lifespan — proper scrubbing stops odour and material breakdown
> Pair it with a water-based toy cleaner, then finish the routine with the G Project Hole Quick Dry Stick to pull out residual moisture. Explore more G Project care tools and the full onahole accessory collection .

## FAQ

### Is the G Project Hole Clean Brush safe for TPE onaholes?

> Yes. Its soft, fan-shaped bristles were engineered for delicate TPE and silicone, so they scrub without scratching or tearing the material. Stiff generic bottle brushes are abrasive and will damage TPE over time, which is exactly the problem this brush was designed to solve.

### How deep does the Hole Clean Brush reach?

> The brush is 247mm long (about 9.7 inches), giving it enough reach to scrub the far end of standard onaholes as well as longer hip- and torso-style toys where residue hides deepest.

### Can I use it with soap or toy cleaner?

> Yes — apply your favourite water-based toy cleaner or a mild soap, work the bristles inside the tunnel, then rinse the brush and the toy thoroughly with warm water. Avoid harsh detergents or alcohol-based cleaners.

### How do I dry the brush after use?

> Rinse it clean, shake off excess water, and leave it standing in a ventilated spot to air-dry before storing. A dry brush stays hygienic and keeps its bristles in shape for the next session.

### What should I use after the brush to finish cleaning?

> Rinsing leaves moisture trapped deep in the tunnel, so follow the scrub with the G Project Hole Quick Dry Stick , which absorbs residual water and prevents mould. Air-dry the brush itself before storing it with your other care tools.
