Stainless Steel LDS Oil Vial Keychain - Ultra Durable, Perfect for Consecrated Oil for Priesthood Holders & Missionaries

Seems solid enough, and if really solid stainless steel (it is heavier than aluminum ones I've previously owned), it should hold up nicely. The opening is wider than many I've owned or looked at, which is very helpful for filling.

Form factor is nice, however the rubber seal broke after keeping it on my keychain for a week. Would not recommend.
