The two pack weighs 206 grams or 7.25 oz in the original package, as measured by my kitchen scale. There isn't a wally-world marking, but the item number on the bag is #750. I posted a link to them on the Orion website. I did notice some online vendors have them, including Amazon.com.

At Orion's site it looks like the bag is white but the ones I bought are in a clear bag. The body of each flare is yellow and instructions for use are marked on the flares. Looks like you take off the cap and strike 'em like matches.

Looks like I pitched the receipt- sorry. But I imagine I'll probably pick up another couple packs on my next trip.
