So, I was Googling around comparing prices on the MOFI sleeves vs the QRP sleeves, which seem to be the same thing. However, I found a budget option that I went ahead and ordered and am very pleased with.
They are rice paper inner sleeves from a company called Check Out Store. The materials seem to be the exact same as the MOFI or the QRP. I notice that (for the most fastidious among us) the corners have a slight curl and the rice paper is slightly wrinkled. To their credit the photo on the link shows both of these issues. They didn't pick out a prime example, they gave a representative one. Perhaps they are seconds from whatever factory makes them for MOFI and QRP. They are very close to identical.
I am using so many that the savings will add up for me. In the group buys, we were trying to get ten ordered to get them down to $.32 each (as opposed to $.40 each and whatever the shipping charge is). If you buy a 300 pack from this company, you are paying only $.20 per sleeve. As the quantity goes up, the cost per gets even lower.
So, long story short, I don't look to be doing any more group buys. I will be using these until either the price goes up or the quality goes down. If anyone wants a couple to try out, message me.
