I belong to the 1st group but will keep the packagings of all my Macross, some of my transformers like MP & Encore series, in case I need to sell them in future. I don't sell for profit, just need to recover some costs back as much possible. In the case of the recent sale of all my 1/48s, the purpose is to make way for storage space & to help finance for the new v2. 1/60 line.
To me, toys are meant to be opened, played & enjoyed. Otherwise I hate the agony of seeing the toys inside packaging & not able to touch or handle it. I wud love to keep a 2nd set as spare but obviously finance is a prblm for me, esp for pricey Macross
