金絲楠木箱
這是老前輩留下來的有個木箱，是金絲楠木做的，到至今都看不到腐爛，裝衣服從來不長蟲，開啟箱蓋香味特別濃，夏天開啟箱蓋手往裡伸的話都特別涼，這木箱長度有75釐米，寬有50釐米，高有40釐米，可見其鉚釘年代久遠，如今市面上找不到這種鉚釘，屬於老木箱無疑。
歷史上，楠、樟、梓、椆並稱為四大名木，而楠木被冠以其首，足見人們對楠木喜愛程度有多高。在中國建築中，金絲楠木一直被視為最理想、最珍貴、最高階的建築用材，在宮殿苑囿、壇廟陵墓中廣泛應用。根據《博物要覽》楠木有三種：一是香楠，木微紫而帶清香，紋理也很美觀；二是金絲楠（楨楠和紫楠的別名），木紋裡有金絲，是楠木中最好的一種，更為難得的是，有的楠木材料結成天然山水人物花紋；三是水楠，木質較軟，多用其製作傢俱。古代封建帝王龍椅寶座都要選用優質楠木製作，同時還是古代修建皇家宮殿、陵寢、園林等的特種材料，該樹種自清代起就稀有了。晚明謝在杭《五雜俎》提到：楠木生楚蜀者，深山窮谷不知年歲，百丈之幹，半埋沙土，故截以為棺，謂之沙板。佳板解之中有紋理，堅如鐵石。試之者，以署月做盒，盛生肉經數宿啟之，色不變也。
楠木之至美者，向陽處或結成人物山水之紋。木質堅硬耐腐，自古有“水不能浸，蟻不能穴”之說。生長緩慢，而其生長規律又使大器晚成，生長旺盛的黃金階段需要上百年，成為棟樑材至少兩百年以上。 主要產於四川是中國獨有的珍貴木材。明清宮廷皇家用材在四川、貴州等地採集。
金絲楠木被稱為軟木之王，在古代是皇室專用木材，百姓不得見，不過寺廟等地可以破格使用，由於極其珍貴，一般只有皇宮裡才會使用，在和珅的罪證中，就有一條私自使用金絲楠木罪，可見金絲楠木之尊貴，此木箱儲存完整，品相上乘，規格較高，具有極高的收藏價值。
