I bought these containers a couple weeks ago, and no problems yet! I have put soup into these and they seemed to be leakproof https://www.amazon.com/dp/B07JK1LGHQ/ref=cm_sw_r_cp_apa_fabc_YG7JNVN5JF1HC99450V4?_encoding=UTF8&psc=1

I bought myself and my spouse these lunch bags 2 years ago, because they like to pack a lot snacks like apples, crackers, pretzels, nuts and such in their lunch bag for work in addition to the food we prep...the glass containers fit into both compartments just fine: https://www.amazon.com/dp/B07FTF6KX2/ref=cm_sw_r_cp_apa_fabc_1MQ2D384WEDEJ5TN3DKM?_encoding=UTF8&psc=1

let me know if you have any other questions :)
