The first bulb came in a 10 x 7 x 6 box with bubble wrap. Installed in my lava lamp and the bulb made an explosion sound in a flash of white light, then nothing (the glass didn't break). I have a thick one, it was an air leak in the piston seal. This bulb was broken. Received a replacement bulb and this time a box of the same size 10x7x6 but without inner packaging. I could only imagine this little lightbulb bouncing around in this big box. I examined the lightbulb and the filament inside the lightbulb was broken. I didn't open the packaging because I knew this bulb would never light my lava lamp. Maybe it's bad quality or careless delivery. This time Revain will not replace, only offer a refund if I return the bulb. So I packed it like they sent me in a 10x7x6 box, only the last bulb was not open with the filament broken and I still had the burned out bulb, put it in there too. My love lamp is still dark. I am 70 years old and if I can buy one in the store I will light my Lave lamp again. Hope this helps someone.
