Review on ☕ JoyJolt Stoiva Double Wall Insulated Espresso Glass Cups – 5 oz. (150 ml) Espresso Shot Glass Cup with Handle – Stackable Thermal Clear Glass Cups - Set of 4 - Ideal for Espresso Machine and Coffee Maker by Charles Butler

Well the mugs arrived in good condition, they were well packaged but they have not withstood many medium loads. I have two out of four left, the first one ran out when I unpacked it, fell off and splintered into small pieces, the second one that I put under the espresso nozzle hit the nozzle and ripped at the rim. The glass looks a bit thin. The other two work well now that I know I have to be a bit more careful and I'm aware that they are very thin or should I say light. But from now on I'll stick with porcelain.
