Non-plastic spill proof straw cups

Looking for a non-plastic (stainless steel, glass, even wheat straw or other alternative) straw cup with a straw that is also completely non-plastic (silicone or part stainless steel) and spill proof. I am trying to find something not too pricey (like less than $10-15 per cup) because I plan to buy like 6 to 10. I hope have them be his milk and water cups for going around the house. I have looked at Elk & Friends stainless steel cups but the straw isn’t spill proof. I also looked at Sursip and Tronco stainless steel cups but the straw isn’t spill half plastic. Same problem with the Zak cups and they are a little bit pricey per cup. Open to reviews of any of these and other recommendations! Thanks!
