Review: Great if your baby is already using straws - Great if your baby is already drinking out of straws and you use boon nursh bottles already. My baby had a hard time sucking with these at first so I had to make the holes bigger but I purchased more when she got the hang of it and didn’t need to make the holes bigger Review: Perfect Transition Straw Top - Absolutely LOVE Boon Nursh products. When it came time to transition my baby to a straw top, she would not use any other top. We already used the boon Nursh bottle since she was born so when I came across this top and I did not have to buy a whole new bottle was so nice. These are so easy to use and clean. The straw detaches for better storage. Great quality and the seal never leaked. My toddler loved to chew on the straw, and it was stretchy and durable enough to withstand her biting it. ## Features - Silicone Sipping: The Nursh conversion top with a silicone straw combines with your NURSH bottle’s silicone pouch for drinks that only touch 100% beverage-safe silicone - Spill Proof Cups: These straw cup lids changes your baby bottle into a no spill sippy cup with a valved straw that creates a spill proof seal to keep drinks in the cup - Flip Top Straw Cup: These Nursh straw cup lids feature a rotating cover that helps keep the straw clean when not in use while keeping their beverages safe from spills while on the go - Easy to Clean: Rest easy knowing that these sippy cup lids are top rack dishwasher safe just like the Boon Nursh silicone shell, ensuring their favorite sippy cups are always ready for a new day - Toddler Cups: These sippy cup lids are for use with Boon Nursh bottles to create a transitional cup for your little one when transitioning from baby bottles to toddler sippy cups with straws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08ZH9H35L | | Best Sellers Rank | #4,908 in Baby ( See Top 100 in Baby ) #133 in Toddler Cups | | Brand | Boon | | Brand Name | Boon | | Closure Type | Flip Top | | Color | Clear | | Customer Reviews | 3.9 out of 5 stars 2,410 Reviews | | Included Components | 2 Silicone Straw Conversion Tops | | Item Highlight | 2 Count, Silicone Straw, Spill Proof Seal, Flip Top Cover, For Use With Boon Nursh Bottles, Top Rack Dishwasher Safe | | Item Type Name | Silicone Straw Conversion Top | | Item Weight | 0.12 kg | | Manufacturer | TOMY Intl. | | Manufacturer Part Number | B11498 | | Material | Silicone | | Material Type | Silicone | | Model Number | B11498 | | Number of Pieces | 2 | | Product Style | Straw Sippy Cup Lid | | Shape | Round | | Style | Straw Sippy Cup Lid | | UPC | 669028114986 | | Unit Count | 1 Count | ## Product Details - **Brand:** Boon - **Color:** Clear - **Item Weight:** 0.12 kg - **Material:** Silicone - **Style:** Straw Sippy Cup Lid ## Images ![Boon Nursh Straw Cup Conversion Tops for Bottles - Image 1](https://m.media-amazon.com/images/I/61GlBOnUy2L.jpg) ![Boon Nursh Straw Cup Conversion Tops for Bottles - Image 2](https://m.media-amazon.com/images/I/71LQyQ9YRiL.jpg) ![Boon Nursh Straw Cup Conversion Tops for Bottles - Image 3](https://m.media-amazon.com/images/I/71EessZku7L.jpg) ![Boon Nursh Straw Cup Conversion Tops for Bottles - Image 4](https://m.media-amazon.com/images/I/71Ic4AzgTqL.jpg) ![Boon Nursh Straw Cup Conversion Tops for Bottles - Image 5](https://m.media-amazon.com/images/I/81D-ooeVk5L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: I have the 4 oz bottles, can i just cut the straws to fit or is there another shorter straw conversion set?** A: They don’t make straws for the 4oz bottles since the smaller size is generally used for younger infants. The straws have bite valves at the top so are more suitable for 9months + of age for which a child is usually using a larger bottle. To answer your question - technically you could cut the straw. **Q: Can this fit mason jars ?** A: No, the threads are different. **Q: Is this a direct match for the grey boon nursh?** A: the straw top fits all of the silicon pouch bottles (4 and 8 ounce or all colors). Our daughter loves them and it makes the bottles usable for a lot longer. **Q: Am I wrong Description states 2 pack but was only one in package** A: It should be two ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great if your baby is already using straws *by D***A on September 19, 2025* Great if your baby is already drinking out of straws and you use boon nursh bottles already. My baby had a hard time sucking with these at first so I had to make the holes bigger but I purchased more when she got the hang of it and didn’t need to make the holes bigger ### ⭐⭐⭐⭐⭐ Perfect Transition Straw Top *by K***. on February 4, 2026* Absolutely LOVE Boon Nursh products. When it came time to transition my baby to a straw top, she would not use any other top. We already used the boon Nursh bottle since she was born so when I came across this top and I did not have to buy a whole new bottle was so nice. These are so easy to use and clean. The straw detaches for better storage. Great quality and the seal never leaked. My toddler loved to chew on the straw, and it was stretchy and durable enough to withstand her biting it. ### ⭐ These lids are a major fail *by A***S on August 9, 2026* We love Boon. We have enjoyed all of their products until this one. Like some other reviews stated, it takes major force to get any water out of the straw. A grown adult has to suck with almost full force to get barely any water. We even tried to enlarge the valve and still could not get water out. Then as a last resort, we cut the valve out altogether and now it just leaks everywhere. We are honestly so disappointed in these lids. ## Frequently Bought Together - Boon Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Boon Nursh Reusable Silicone Pouch Baby Bottles - Medium Flow Nipple - Silicone Baby Bottle Pouch and Nipple - Baby Feeding Essentials - Color Block - 3-6 Months - 3 Count - 8 Ounce - Boon Nursh Silicone Baby Bottle Nipples - Bottle Nipples for Boon Nursh Baby Bottles - Baby Bottle-Feeding Supplies - Fast Flow Baby Bottle Nipples - 3 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/299104890-boon-nursh-straw-cup-conversion-tops-for-bottles](https://www.desertcart.at/products/299104890-boon-nursh-straw-cup-conversion-tops-for-bottles) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-16*
