Size 40 do not come in the RH you need to keep IT fresh. Size 67 in either 58% RH or 62% RH is what you'll need to preserve up to 453 g. Here's a link to our 4 packs of each RH, so you can decide which one is for you.

@@rubenpm2525 Right. I'd use one Size 67. You can never overhumidify by using more Boveda than recommended. It will work more efficiently and last longer. Ok to use four Size 8, too.
