Q1: What is the exact liquid capacity, weight, and what comes in the box?

Q2: How does the 1-piece removable stainless steel tea strainer work?

The included food-grade 304 stainless steel strainer is a single, easy-to-use 1-piece basket with a flip-up wire handle that snaps securely into the neck of the bottle. You can use it in two ways: (1) place loose-leaf tea Directly inside the basket, pour in hot water, and lift the basket out by its wire handle once your tea has steeped; or (2) place larger tea leaves, herbs, or fruit slices in the bottom of the bottle and leave the strainer snapped into the neck as a filter guard while you sip. You can also remove the strainer completely to use the bottle for coffee or everyday water.

Q3: Why is the product brand listed as "Generic" while the store is "AI Master™"?

AI Master™ is our online retail storefront name and AI Master LLC is our registered California company (CA Secretary of State Entity # B20260165948). We source this 15oz bamboo water bottle from an established wholesale drinkware manufacturer and sell it as an unbranded (Generic) product—meaning the natural bamboo wood exterior has no brand logo printed or laser-engraved on it (only the standard SUS 304 stainless steel grade stamp on the interior metal base and tea strainer). While the physical bottle is unbranded (Generic), AI Master LLC takes 100% commercial, legal, and operational responsibility for product quality, U.S. warehouse fulfillment, returns, warranty coverage, and customer support.

Q4: How do I wash and care for my bamboo water bottle? Is it dishwasher safe?

Hand wash only. Because the exterior shell and lid top are crafted from real natural bamboo wood, do not place the bamboo bottle or bamboo lid in the dishwasher, microwave, or freezer, and do not soak or submerge the exterior wood in water. Wash the stainless steel interior, 1-piece tea strainer, and lid by hand with warm water and mild dish soap, wipe the bamboo exterior dry with a towel, and allow the bottle to air-dry uncapped between uses.

Q5: Where does my order ship from? Do you dropship from overseas?

We never dropship from overseas. All inventory is pre-purchased, owned by AI Master LLC, and physically stocked in United States Amazon Multi-Channel Fulfillment (MCF) warehouse centers located in California, Texas, and New Jersey. Please note that our registered corporate address at 10422 Tank House Drive, Stockton, CA 95209 is strictly our administrative office (with no walk-in retail customers)—all customer packages ship directly from our U.S. Amazon MCF warehouses in California, Texas, and New Jersey.

Q6: How much does shipping cost and how long does delivery take?

Q7: Do you ship to Alaska, Hawaii, P.O. Boxes, or internationally?

Q9: Are there any hidden checkout fees, and how is sales tax calculated?

AI Master LLC holds an active California Department of Tax and Fee Administration (CDTFA) Seller's Permit, and any applicable state or local sales tax is automatically calculated and shown on your checkout screen based on your shipping ZIP code before you authorize payment.

Q10: What is your 30-day return policy, restocking fee, and original shipping refund rule?

Under our Return & Refund Policy, you may return any unused, unwashed bottle in its original packaging with all 3 included parts within 30 calendar days of delivery.

For standard buyer's-remorse returns of unused items, the customer pays for the return shipping label using a trackable carrier and receives a 100% refund of the $18.18 USD purchase price plus any sales tax paid.

Q11: What if my bottle arrives damaged in transit, defective, or missing a part? (72-Hour Rule)
