Armor pieces formerly produced for an organization of nocturnal athletes [descriptive accuracy forbidden].  Exclusivity contract expired - partially finished kits now available for general distribution.
 
Kits include all pieces required to build a pair of shin guards.  Choose between two spiked variants and a non-spiked variant.  All spike color options feature a silk sheen.  Straps include an elastic buffer to help keep the armor in place, and do not require any sewing.
 
Steps required [a guide with further tips is included]:
Cut out armor shells using a razor.  Styrene is easy to work with.
Drill mounting holes and clean up edges.  Shell surfaces should require very little sanding, if any.
Paint, if desired.
Install spikes, if applicable.
Install pre-sewn strap assembly.
 
Tools required:
Box cutter or similar sturdy razor
1/8" drill bit
5/16" drill bit (for spiked variant)
Sandpaper/files
2mm hex wrench
 
Skill level: Easy (just cut away from yourself, please)
Time level: Low, plus paint dry time
 
[Q: Can I buy a finished version?]  No, sorry - while these should be easy for one person to make for themselves, various personal factors make them unsuitable for mass production.
