Reclosable outer record sleeves

I'm running out of outer sleeves.  My last order of sleeves was from Red Trumpet (anyone remember those guys?).  I ordered 1000 Japanese resealable outer sleeves.

I can't seem to find those same sleeves anywhere, so I was hoping the collective knowledge of this forum could steer me in the right direction towards a suitable substitute with a reclosable flap.

Thanks in advance.
