Zak Designs

Free shipping applies on orders over $45. Below that, standard shipping within the contiguous United States costs $3.99 to $5.99, which the page publishes openly rather than leaving to checkout. Since this two-pack is $16.99, you would need to add further items to reach the free shipping threshold.

Zak offers free, no-hassle returns for 30 days after purchase, which is clearly stated on the listing. The detailed refund policy sits on a separate linked page, so read that for conditions. Note that no contact email, telephone number or trading address is published, only a contact form, so initiate returns through that route and keep a record.

No to both, and the page states this clearly. The tumbler is designed for cold or room-temperature drinks only and is not microwave safe. This is worth taking seriously with a children's cup, because hot liquid drawn up a straw goes straight to the mouth and throat and presents a real scald risk. Use it for water, milk and chilled drinks only.

The cup can go in the top rack, but the brand recommends hand washing to keep the printed design bright, which is honest advice rather than a disclaimer. Keep it off the bottom rack, where the heating element will warp plastic. The page also advises against using straw brushes, since they damage the valve, so disassemble the lid fully and soak and rinse the straw and valve thoroughly instead, because these are the parts where mould and bacteria accumulate in straw cups.

It is recommended for ages three and up, and the straw is specifically designed so that a child cannot pull it out of the lid, which addresses a genuine choking hazard that loose straws present. The materials are described as BPA-free plastic and silicone. Two things the page does not state are the specific polymer used, which affects durability and heat tolerance, and whether the product meets CPSIA requirements, the US children's product safety standard covering lead and phthalate limits. If that documentation matters to you, request it through the contact form before ordering.

Possibly a little, and credit to the brand for saying so rather than letting you discover it. The page states that a small amount may leak if a heavily filled cup is left on its side for an extended period. In practice that means it is fine upright in a cup holder or on a table, but pack it upright in a bag rather than lying flat, and do not fill it to the very brim if it is going into a rucksack.

It holds 15 ounces and measures 6.67 inches tall by 3.16 inches in diameter, which the page publishes so you can check fit before buying. That diameter suits most car cup holders and standard lunch bags, but measure yours if space is tight, particularly for a child's booster seat or a narrow backpack bottle pocket.

Every Zak Designs code listed on smartstorereview is tested against the live checkout before publication and rechecked regularly, with expired codes removed and the last verified date shown beside each offer. Note that Zak also runs a separate 15% discount programme for military and veterans, first responders, healthcare workers, teachers and students, which may be better value than a public code, and that reaching $45 removes the shipping charge entirely.
