I don't mind ugly packaging at all. One thing that drives me crazy is when someone mummifies delicate glass with tape. It is hard to dissect the glass without breaking the glass. I use only a single piece of tape when packing, with a piece of paper tucked under the end, so the recipient can just lift to open.
The only glass that I have had to break was a beautiful Salviati glass that was double-boxed. I did not leave enough room between the outer and innner box, so the inner box broke the glass when the outer box was compressed -- dumb of me with this rare glass. I don't double-box anymore. I just use a large outer box and a lot of bubble wrap and peanuts. It seems to work better making the inner box out of bubble wrap.
