Hi all. I thought I saw this posted here but a search came up empty-handed. I brought back a couple of pen shells from my recent trip to Florida. What should I do to prevent them from cracking? That used to happen to me all the time when I used to collect down in Texas. Mineral oil? Glycerol? Any other suggestions? Thanks.
