PRODUCT REVIEW: WRMK Slimline Punch Board + Metric Measurements

Here's a first look at the new We Are Memory Keepers Slimline Punch Board.
Apologies some of the video is out of focus, I think all the important parts are visible and I will include the measurements below. Thanks and enjoy!!

Imperial Measurements are always available from the Board. Metric Measurements are below, noting they are rounded a little where the exact mm measurement is of no consequence. Shout out with any questions.

Standard Slimline Card and Envelope:
Finished Envelope = 4 x 8 3/4 inches OR 10 x 22cm
Card Size = 3 1/2 x 8 1/2 inches OR 9 x 21.7cm
Starting Envelope Paper Size = 9 x 11 1/2 inches OR 23 x 29 cm

Mini Slimline Card and Envelope:
Finished Envelope = 4 x 6 3/8 inches OR 10 x 16cm
Card Size = 3 1/2 x 6 inches OR 10 x 15cm
Starting Envelope Paper Size = 9 x 9 inches OR 23 x 23 cm

C6 Envelope:
Finished Envelope = 114 x 162mm
Card Size: 105 x 150mm
Starting Envelope Paper Size = 240 x 230 mm

Gusseted Envelopes:
These sizes relate to the Standard and Mini Card Sizes above. The largest gusset you can achieve with a 12 inch piece of patterned paper is 1/4 inch. Alternatively you can use the same calculation method to build a deeper gusset by adjusting for a smaller card.
Standard Slimline Paper Size: 9 1/2 x 12 inches OR 24 x 30.3cm
Mini Slimline Paper Size: 9 1/2 x 9 1/2 inches OR 24 x 24 cm
Cut and Score as normal, and BEFORE moving on to other corners make a second set of score lines 1/4 inch (6mm) in from original score lines. To do this move the paper out and up 1/4 and inch. NOTE: Place 1/4 inch (6MM) strips of washi tape on the outer guide of the board to help to get the lines straight
